There was a post in AIBU about a father co sleeping with his 3 year old while masturbating / watching porn. Lots of helpful but shocked replies spelling out to the OP that this was very much not OK.
The deletion message by MNHQ reads
"Hi all,
We are removing this thread as it has become a nest of trollhunting and impossible to moderate. Once again trollhunters are preventing MNers from receiving valuable advice."
This is massively misunderstanding the whole post and replies! Many responses were reporting the thread to ask MNHQ to take action. I read all the posts before deletion and didn't see any trollhunting. So disappointed by this deletion message MNHQ .
