Me too, the oficial response seems to be this one
There was an issue while filtering through duplicates before the airdrop and people who shouldn't have been removed were removed. Following the initial distribution I realized this had happened so I started giving my own eBTC away to anyone who signed up and didn't receive their tokens. I gave more than half of my holdings away, and stopped after 24 hours of it. I wish I had enough tokens to give to everyone who experienced this but I do not. I hope you guys can understand.
