Your immediate thought upon seeing someone named "theymos" (or any other recognizable name) on any other site is that he's not really me. Typically, anyone can register whatever name they want, so you should treat a username as total non-evidence. In this case it's especially obvious because if I wanted to sell highly-ranked accounts, I would just create accounts with Ultra-Legendary status, 1 million merit, +9999 trust, etc. and sell those. (But we never do this sort of thing, either.)
If I tried dealing with every impersonator, I'd spend tons of time on it and still fail to catch them all. If you care about the site in question, you can report it.
That's true I'm also a forum administrator since I own a local forum and I can do that easily, in fact there is an option to upgrade accounts create rank in simple machines script , so don't be misled by that advertisement why would Theymos do that made no sense to me.
