He has an option to prevent posts from being Merited: his thread is self-moderated. If reports are inaccurate, he can simply delete them and nobody can Merit them anymore.
This is probably something I should know, but deleted posts don't invalidate any merits given to them, do they? And I guess that's a way of enforcing the local rule, it's really not a viable option unless the report is eventually deemed inaccurate and Timelord2067 wants it scrubbed entirely.
Because (IMO) that's what the merit system is for - to merit good posts, not just to give bags of merits to users.
Point taken, suchmoon. That's not to say I'm going to give up taking that particular shortcut, but I respect your views.
Let's move on.
Sounds good to me!
