When your account was debited of that same amount,why don't you report to admin of Airhawk-project?.On the issue of multiple account,I don't really know if any measure can be taken against that.Alot of people operate multiple accounts,am not justifying their greed,but they use different information ,like different phone number, emails and avatar,so if steemit can work with Google or any emails provider they may find lasting solution.HOW EVER I BEG YOU PEOPLE DON'T SPOIL THIS PLATFORM FOR LEGITIMATE PEOPLE.This is not a platform for FRAUDSTERS STOP SPOILING OUR NIGERIA IMAGE PLEASE.Thanks for sharing this information @flame-man
