Create A Forum - Support Forums

A person on an online forum, for a while, had been impersonated by a sociopath who wants to ruin his life.

Then, he managed to regain his identity, as well as the forums itself.

Now, said sociopath stole his account there.

Is it possible for him to get it back?

(For reference, it's at http://shanescavestory.createaforum.com/ and I've deleted my account there in anger. {Or, at least tried.} )
