Reminds me of a time a while back when a friend of mine, despite my constantly trying to remind him how terrible of an idea it was, tried to make a faction that was basically space furries -- wolves, raptors, etc.
It was received poorly by the community, and for good reason. He eventually changed his faction to something a bit more fitting.
I believe the same should go for this "MLP". If they have an inRP faction that fits in with disco lore and name their ships after ponies, that's fine. But from what I've seen they don't RP.
