The Bitcointalk airdrop was fake and not initiated by us, we also mentioned in the thread.
So there hasn't been one?
Please, check official social media channels from Signals Network because probably you got into a 'fake' aidrop of SGN token. There wasn't any official airdrop from Signals team.
I noticed that too that there a lot of fake airdrop announcements in Twitter. I think some are just trying to get a lot of followers and others might be getting important info to try to scam people. So be careful out there.
