DEX: what are these “airdrops”?

I have a small balance on a DEX to screw around with some of the better known meme coins (BONK, PEPE), plus a little ETH for transaction fees.

Some other stuff has appeared- chickencoin, pigcoin, wildgoatcoin, and others. Usuall 20-100 coins, valued under 5-10 cents total.

Is there a site to vet/check out these tokens? Or are they scams/contracts of some sort? I just don’t touch them.

Gotten some other odd stuff too, listing of $10,000 USDT, $50k of “ETH-BONUS.NET”. I assume these are bad contracts designed to drain your wallet if you interact with them, so I don’t touch them.

Just ignore all these? Any way to get rid of them?
