Bounty
Zorbak (250 ECOMT) helped me to find out
SCAMMERSThank you so much, has been a pleasure as I am tired of people usurpating btc ID which lmakes a lot of legit users out of airdrops because of doubles.
I advice to all people participating in airdrops to write their address in location, so in case of doubles, we can check the legit user.If there is a double with same info, I just kept one, so all participants gets 1 airdrop (we can all make the mistake to register twice, we are humans)
If double with different information I checked profile to confirm the address and delete SCAMMER.
