How bout a suggestion, for closing thread / deleting post and require notice thing.
I've seen a few times, the advice for finding out what happened is to PM the mod who did it, but does closing thread / deleting post lets the poster know who did it?
So, lets say there's a system notifying the said TS / poster about which mod did the closure, the complaints wouldn't pile up in here, instead they'll PM that said mod.

Hope I explained it clearly.
