Linea Filtered Out 40% of All Airdrop Claimants as Fake Wallets

Linea, an Ethereum layer-2 network, filtered out 516,960 of 1,297,203 addresses claiming its token airdrop — nearly 40% of all claimants — as "Sybils": fake wallets run by the same person or script, The Block reports.

What a Sybil attack actually is: one participant creates many separate wallets that look like independent users, in order to claim a disproportionately large share of an airdrop or reward — instead of honestly claiming one share as one real person.

How it's actually detected: Linea worked with analytics firm Nansen to look for signs of automated, coordinated behavior — like identical gas bids and identical gas limits across hundreds of transactions in a row, since real humans always show some variance in those settings while scripts don't, CoinMarketCap notes.

What this means in practice: most major airdrops in 2025-2026 now run similarly aggressive filtering, and AI-powered detection tools like Trusta Labs have become the industry standard. For an honest user, that's actually good news — each real participant's share of the reward gets bigger once fake wallets are weeded out ahead of time.
