You know the first won't happen. Self moderated threads are self moderated and the OP may do so as they please; they've been there since the inception of the forum with "Local Rules".
This is not true. Scammers have been given "hidden scammer tags" in the past that prevent them from deleting posts in self moderated threads. The most recent example that comes to mind that I was able to get this applied to was TheGambler and his alts. I am unsure if Vod's most recent transgression is sufficient to earn him similar restrictions.
If you are serious about this then please PM me contact details and I will get you a PGP signed address to send to.
