Hope I am posting this in correct section.
Suppose an Altcoin plans to Airdrop exclusively to Bitcointalk Forum Members, how do they authenticate whether the participant is a member of the forum or not?
I have seen some bounty managers asking members for an authentication post like following, but is this okay as per forum rules?
Authentication for blahblah coin:
Telegram username: blahblahtelgram
Twitter username: blahblahtweeto
Also, bounty managers like needmoney just ask airdrop participants to post their profile link. I feel this is not a fool proof way to authenticate as anybody can post anybody's profile link.
Is there any other way one can authenticate bitcointalk members without breaking any rule??
Thanks
