Do not worry guys it was airdrop but this group which bought eBTC are contacting a lawyer, from what I read from the group, his IP adress logs are there.. He scammed people, maybe had fun, but his ass will suffer soon as it seems  
Also the dev was logged in today in bitcointalk so there is nowhere he can run. He is very naive if he could though he is safe behind the PC, he should watch Edward Snowden documentary
