Getting of thr Forums

I posted an item years ago about PSPICE and now I just get spam (Several today).  But when I logged in it created a new account. Maybe because it was years since I posted.  So I know have a zombie account on this site spamming me.  Can some one explain how I fix that.? I'd be happy to delete the account.
