I really don't understand why people still continue to join airdrops that will give you in best case less than 5-6$ in coins..... and asking for KYC is absurd!
Some ask for KYC only to avoid multi accounts (?) or to comply whatever laws (?). Some others, indeed, can do quite a lot of "interesting" things with those documents.
On another hand, too many (especially starters) are desperate for a few free bucks and you can't imagine how easily people give their ID.
I would suggest you make a tutorial for airdrop/bounty newbies, but I guess that most will not read it...
