Is Chainlist safe to use?

I was wondering if chainlist is safe to use?

Some token I hold is asking all their users to connect our MM wallet to chainlist because they're doing a airdrop of another token and its listed in Chainlist and want to use it to import it.

What is its use anyway? Can't I just manually add that token in MM?

I don't feel comfortable connecting my MM to any site no matter how safe that is but they're saying if I don't do that step I will not receive airdrop…
