I do not believe that ajuravi007 or asdfgf created fake ids. Not sure about Vivek Sharma (not very likely according to me. If you notice, he types in caps most of the time).The prime suspect is amatan aka hitler aka ajuraviOO7 aka ajuraviO7 aka asfdgh aka many-other-copycat-ids-which-were-banned-soon-enough. And the question wherein you ask the meaning of aka is in reply to a post by him, not asdfgf.
