Hi,
I'm new on bitcointalk, but not in crypto. Last few weeks I've joined in more airdrops and I've realized that almost every ERC20 token airdrop has he same problem.
Coins developers must fight with a lot of people registered multiple addresses! These people then sell their tokens under "expected" price and makes dumps.
I think that airdrop admin has the possibilities to find out these guys and it will be good to have a list of these people for other admins (developers) to avoid them.
I know that it won't be easy, but maybe it's not impossible. So take this just like an idea.

PS: I hope that I won't be on one of these lists if it will be created
