A few things will get you filtered almost every time:
Sybil behavior — running multiple wallets funded from the same source, doing identical transactions across wallets in the same time window, or having wallets that clearly share behavioral fingerprints. More on this below.
VPN and bot signals — many projects track IP addresses and device fingerprints. Wallets that all originate from the same IP, or that show automated patterns (constant transaction timing, robotic interaction sequences), get flagged.
KYC/geography restrictions — US users are excluded from many airdrops for regulatory reasons. Projects that require KYC will disqualify wallets whose identity doesn’t match, or residents of restricted jurisdictions.
Missing the claim window — not technically a disqualifier, but you’ll lose your allocation if you don’t claim in time. This happens more than people admit.
Using exchange wallets — if you didn’t use a self-custodial wallet when interacting with the protocol, you likely won’t receive anything.
