There is actually a possibility that this one was created by sirus as it has a single post from 2012.
It would still be unwise to do any kind of business with it though.
Right.
AFAIK facebook has a real name policy, so I don't know if that account can be used anyway.
I think scammer created a page by that name

Bitcointalk.org can contact facebook and get this account removed or still better this name given to forum for fb account
