So I see that these scammers are still using that "Radium X" for fake ANN threads, like years ago...

Regarding Harizen, it looks like hacked account as I see no change of password and/or email and it doesn't make much sense to sell Legendary account with solid reputation and that is in a signature campaign. Then again, stranger things have happened here. Either way, hopefully he realizes soon what happened so he can get control of his account back.
