Generalizing so as not to be TATT.
I've noticed a few times recently, that a thread will be removed where the OP's thread/OP post will have nothing wrong with it, it's just that presumably a few of the commenters supposedly broke the Talk Guidelines.
This seems a bit mean on the OP and surprising.
Couldn't the supposedly offending posts by others in the thread be removed instead?
I suppose it does depend how many people are responding to a post on the thread that might not be ok and ends up deleted. If there are a lot of them the thread might end up with so many posts which quote a deleted post that the thread becomes hard work for MNHQ and looking messy.
