How to find 'eligible' airdrops for yourself?

EDIT: Solved, too good to be true is too good to be true except if it's ARB, lol

Hey all!

Since the ARB airdrop which I almost missed, I'm a bit more eager hunting for airdrops I've been eligible for. Now there is a website which I won't link but is called earnify. When I pasted one of my wallet addresses in, it says 1481$ to claim.

How would one go find this yourself? I'm very skeptical of the payment required to see which airdrop on the website and I actually suspect it is false. But hey, 1K is nice money, so I'd figured it's worth asking here..

Googles on that website only leaves me with reviews or articles such as 'I paid and one month later cancelled' but also this I don't trust.

Are there maybe a few bigger airdrops in the past that are still valid to claim, if so how do you find those? I've used mainly eth and polygon.

Please don't DM, they are turned off.
