On the blockchain #TON (The Open Network), there are several projects known for their generous and relatively honest airdrops without obvious signs of fraud.

Notcoin - One of the most famous projects on TON, which distributed more than 90% of its tokens #NOT among 35 million users through a Telegram bot. The airdrop was based on activity in the game, and many users received significant amounts without complicated conditions. The project has established itself as transparent, although with some limitations on withdrawals.

Dogs - this project conducted an airdrop of 1.75 billion #DOGS for more than 400 thousand users. Participation was through quests in the ecosystem, and tokens were indeed distributed; all the rest was pure scam.
