It's not just pony stuff that is in the folders when it shouldn't be. Here's a full list of things I've found that aren't in the right folders or don't belong in this group, including a lot of other unrelated robots(and it really doesn't matter if they share universes or not, if there's no transformers in the work at all, it really should not be allowed, with the sole exception of the altmode and parts folders for obvious reasons, the items folder could probably also get a pass but I really think it should just be transformers-related stuff as well):
