Being flagged as a Sybil in an airdrop is not a death sentence. Most Sybil reviews rely on clustering algorithms. As long as your address actions were performed by a real person but got caught in the crossfire due to batch interactions, shared deposit channels, or tool‑use habits, there is still room to appeal — the key is to present traceable on‑chain behaviour evidence, not empty words.

Step 1: Figure Out Which Sybil Rule You Triggered
When a project labels you as "Sybil," you usually don't receive a detailed explanation. You need to backtrack yourself and divide Sybil judgments into three categories. The appeal strategy differs completely depending on the situation.
Situation A: Fund‑Linkage Type
There is a clear fund‑flow link between your address and many other addresses — for example, gas fees were distributed from the same upstream address, funds were gathered, or multiple addresses were topped up in the same time window through the same CEX account or cross‑chain bridge.
- Self‑check method: Open the block explorer for the relevant chain (Etherscan / Arbiscan / Solscan, etc.), enter your address, click "Analytics" or "Graph," and look at the incoming fund nodes. If there is a transaction from one address that sent small amounts of ETH to hundreds of addresses at the same time, you were swept into that cluster.
- Common reason for failure: You withdrew coins from the batch withdrawal interface of an exchange like Binance or OKX. The exchange's hot wallet sending funds to a huge number of addresses is solid proof in Sybil detection. You did not isolate your funds beforehand.
Situation B: Behaviour Pattern Type
This mainly looks at interaction timestamps, the sequence of called contract functions, and the gas price settings. For instance, hundreds of addresses calling the same functions on the same batch of dApps in the same minute, or gathering to operate on some obscure, rarely‑used contract.
- Self‑check method: Pull your interaction history using DeBank or Zapper, compare it with other addresses that were flagged as Sybil in the same batch (if someone has published a list), and check the concentration of interaction time periods. If your operation times overlap heavily with others, you were most likely grouped into a "behaviour similarity cluster" by the algorithm.
- Risk reminder: At this point, absolutely do not create a bunch of new addresses and use the same method to farm the next project to "recover losses" — your operation fingerprint has already been recorded, and some Sybil analysis platforms (like TrusaLabs, Chainalysis) share feature libraries across projects. Continuing like this will only make your address correlation graph look worse.
Situation C: Credential Overlap Type
You and other Sybil addresses hold the same NFT, domain name, or Gitcoin Passport credential combination, especially credentials verified by snapshot.
- Self‑check method: Go back to the project's snapshot time, check which ERC‑721, SBT, or DID credentials your address held at that moment. Then look at the holder distribution of those tokens on OpenSea or the relevant explorer. If you find that the holders are teeming with Sybils, you have fallen into a credential contamination trap.
Completion standard: You should be able to summarise in one sentence the actual reason you were flagged as a Sybil, and find at least one on‑chain transaction that proves you are a real human (for example, buying a token long before the Sybil cluster appeared, or interacting with a dApp via a path that differs from the cluster).
Step 2: Organise the On‑Chain Behaviour Evidence Chain for the Appeal
An appeal ticket usually only has one text box and allows only a few image attachments. You must speak with publicly verifiable on‑chain data. Do not write a long personal story.
Three types of evidence you need to collect:
- Proof of Fund Origin
If your gas fees or operating funds came from a CEX, provide the exact transaction hash (tx hash) of the withdrawal from the CEX to your address, not just a screenshot.
- How to do it: Find the corresponding withdrawal transaction ID (TxID) in the withdrawal history of Binance or OKX, then open it in the block explorer and capture the page showing the exchange hot wallet address, your receiving address, the amount, and the timestamp.
- Risk reminder: If your CEX account once withdrew to dozens of addresses in batch, that tx itself is already on the Sybil exposure list. When appealing, do not avoid it; you need to additionally prove why you needed multiple addresses (e.g., you manage multiple test accounts, you guided a group operation, etc.). Lying that it is your only account will be easily exposed.
- Independent Operation Traces
Find one or several interactions that only you would have done — for example, providing liquidity on an obscure protocol, buying a non‑mainstream NFT, or participating in an early‑stage test of a small project (with the interaction time predating the appearance of the Sybil cluster).
- It's recommended to use a Dune query or the DeBank timeline to mark the interaction times. Provide the tx hash and an interaction screenshot, and also include objective data showing the protocol's extremely low TVL to explain that this is "non‑Sybil behaviour."
- If you want to understand further how to look up the historical interaction data of a protocol, you can refer to the article "Introduction to On‑Chain Data Queries: Use Dune to Build an Address Profile" to supplement your basics.
- Human Identity Link (only when necessary)
Some projects accept a Gitcoin Passport score, the holding period of an ENS domain, or POAP attendance records as supplementary evidence. The key point is that these credentials must have been bound before the Sybil snapshot was taken.
- Completion standard: You can provide more than three externally verifiable credentials, and they point to a real identity that has been continuously used for more than six months. Do not submit credentials that were minted temporarily after completing a Sybil task; that will only reduce your credibility.
Step 3: Identify the Appeal Channel and Write the Specific Content
To find the appeal entry, go through three channels: the project Discord's "appeal" or "support" channel, the Google Form / Typeform posted in the official Twitter announcement, and the Sybil‑report discussion area some projects set up on GitHub.
Follow this framework directly for your written structure:
- First line: Paste your address and the corresponding Sybil judgment number (if any).
- Second line: Explain in one sentence why you do not belong to that Sybil cluster — "My address was wrongly grouped into the Sybil pool because I withdrew gas fees from Binance (TxID: 0x…), but the subsequent interaction times, amounts, and paths were all independent operations."
- Next, list 3–5 pieces of evidence, each in the format "Evidence type: on‑chain tx hash + one sentence explaining why this proves a real human."
- Last line: Leave an email or Discord ID where you can receive a reply, and voluntarily state that you are willing to cooperate with a secondary KYC verification.
Situation A: The project requires KYC verification
You need to submit a Gitcoin Passport score or record a video that includes your transaction history. The video is recommended to simultaneously show you logging into your CEX account, opening the withdrawal history page, then opening the block explorer to query that transaction.
If you don't yet have an independent, KYC‑verified exchange account, you can open a new account specifically for handling appeal matters and complete the identity verification. The purpose of using a new account is to cut ties with the fund pool suspected of Sybil activity and prevent linkage.
Common reason for failure:
The appeal text only includes a bunch of screenshots without a clearly provided tx hash. Reviewers process thousands of appeals a day and won't look up on‑chain data for you. Tickets without a tx hash are basically closed directly.
Step 4: How to Prevent a Second Judgment After Submitting
Before submitting, put your address into a "behaviour silence" — do not make any further interactions, especially do not transfer any tokens or empty the wallet; otherwise, the project team will think you are creating disturbance links during the review.
Waiting period:
- Usually it takes 1–4 weeks to get a result. During this time, politely ask once every 3–5 days in the corresponding Discord channel using the original ticket number; do not open a new ticket.
- You can check the review status via the project's public Google Sheets or a Dune dashboard (if the community has created one). If there is no public tracking page, you just have to wait for an email.
If you receive a notice during the waiting period asking you to pay an "appeal deposit," stop all operations immediately.
No legitimate project will ask you to pay money to remove a Sybil label. This is a typical feature of a secondary scam. Immediately present the evidence publicly in Discord and contact a moderator to ban the scammer.

FAQ
Q1: If the interaction tool I used (such as gas‑free dispenser, batch transfer tool) was flagged, is an appeal still useful?
It depends. If you only used these tools to manage your own dozen addresses, you can submit the tool's principle and your own deployed contract address as part of the evidence chain. But if you used a public tool contract that hundreds of people call simultaneously, it is hard to separate. In that case, it is more effective to prove your independent identity on other chains (for example, early interaction records on StarkNet) and reduce suspicion through cross‑chain behaviour.
Q2: After the address is removed from the Sybil list, can the airdrop still be claimed?
Most likely yes, but when claiming, pay attention: Do not gather funds again through those flagged "recharge channels." Create a new, clean receiving address, and withdraw a small amount of gas directly from your hardware wallet or a KYC‑verified CEX account for the claim. Before the claim is complete, do not mix with any Sybil address through the same relay wallet.
Q3: The project says the appeal failed. Can I submit again using a different account?
It's best not to. The Discord account, email, and IP information you use for the appeal will all become linkage dimensions. If a second submission is found to be from the same applicant, you may be blacklisted directly. If you confirm that you have new strong evidence (for example, discovering an earlier, obscure interaction), supplement it under the original ticket. If the original ticket is closed, when opening a new ticket you must clearly state "supplementing new evidence for the previous ticket" and proactively reveal the connection.
The next step is clear: after submitting the ticket, keep the address at zero interactions, and check the project Discord announcements and the reply status of your ticket once a day. If there is no movement for 3 weeks, and the project has opened a new batch of appeal channels, you can resubmit once together with your original ticket number. After receiving the approval notice, make sure that all addresses you will use to claim the airdrop in the future have completely detached from the previous fund‑linkage network before executing any on‑chain operations.
