Sometimes it feels like the rules are arbitrary and very... one way.
Like threads get moved, but others of the same quality wont.
I'd wager that the reason for this being the case is that some offenses have reached a point where they have been accepted by the forum as a whole as not being wrong.
VS threads in the VGD or A/M/C forums are and have always been against the rules but they have become a part of the 'culture' of each board. As a result, very few people think that they are actually in violation of the forum rules. Depending on how new forum assistants or moderators are, they might never have known a time when these types of topics were strictly controlled.
Additionally, moderators/assistants/whoever else are only human. Many reports are likely responded to on a case by case basis and if Moderator A believes that something is okay but Moderator B interprets it differently and deletes/moves a thread neither of the two is technically 'wrong'.
It's just a natural consequence of having statute based law rather than precedent based.
