Yeah, scammers are in a continuous look for different ways to catch people that are not careful/informed enough. Another thing that I simply love at this place is the way people can identify themselves, because if you hold the private keys of your account, you can prove your identity just making a post. Nobody will be able to create an account with the exact same name, and if they make one with a pretty similar name, they will not be able to reproduce the reputation of a whale or dolphin so easily and eventually soon they will be flagged to nothing.

Look at the bright side, you are an important person who deserve the attention of a pretty big audience, since your account is replicated by scammers :D
