Just saw this while I was on Etherscan a moment ago, if you check this address : https://etherscan.io/address/0x7e3d7d8e31b3f472fcd3c1552a9f009131c50c6c#comments , it seems some scammer has cleaned out a ton of accounts yet again. I was one of those caught by the OmiseGo airdrop scam a couple of weeks ago and it was so disheartening. Be careful out there and never ever give out your private keys!
