A serious question, why do MN do this?
It seems to be a regular occurrence that an OP will start a thread, when they do not the response they want they will then have a tantrum, start telling posters they are wrong, etc. and MN will then delete the thread.
I don't agree with closing down threads just because someone disagrees (rather than say libel or other legal issues, or personally identifying information), however outside of those circumstances it seems excessive to delete the threads even if there is an underlying mentality of wanting to close down the debate, surely it would make more sense to leave them standing as a record of what has been said, even if they are locked so that no one can post any further (which still seems excessive)?
What is the reasoning behind the daily deletions of threads that happens purely because the OP has a tantrum?
