Wow, it's an homographic attack, isn't it? They've copied your avatar too. For certain stuff (I think about e-mail and http clients, e.g. browsers) it seems to me we still have naive implementations in place. If you look to URL on the address bar on Chrome, it's almost impossible to notice the difference with the regular one. It's enough to copy & paste the URL on a text editor, maybe with a better font (Consolas in my case), and it's easy to spot on fake account that the third letter is a capital i (like "Impostor"). Did you face similar attacks in the past? Is Github fast enough to fix it? Does it help if I ask too Github (and other volunteers) to block account for deceiving content (or whatever)? Are more requests going to speed up the verification process? This is really nasty stuff! :(
