Don't you think that most of the airdrops you are posting are nothing but a try to collect your data to sell it? I mean why on earth would somebody need my e-mail adress, twitter, telegram and my bitcointalk profile just for sending out an airdrop?
I agree with you, that's why I made a new email just for crypto, I never use my twitter and telegram so they are just for signing up.
And especially never share facebook account! Crypto world = total privacy.
One question. On telegram, is the telephone number private or everybody can see / take it??
