I got an email and its safe to assume that the email was picked form one of the airdrops.
Not sure if this site is legit or not, however its safe to assume its not since the domain name was registered on 8/30/2017. Please don't provide your information for this airdrop as I did not read anything about free OmiseGo tokens.
Fake site: https://omisegotoken.com/airdrop/Original Site: https://omg.omise.co/No matter what, don't send any information to the above mentioned fake site.
Hope it helps.
I saw this posted on twitter a while back. I started the registration process and when it asked me for my private keys I laughed at the screen. Part of the problem is that the OMG people were quiet on the airdrop procedure. All the information they posted was that it was coming and nothing else, this left the door open for the scammers to step in with an official looking website. Some guy on their twitter feed claimed to have fallen for this scam.
First rule of Crypto - Your private keys are private for a reason. Whoever has them has access to your coins.
