Well, I actually meant something like people posting an addon related to MLP and then people saying "UMG KEEP IT IN THE THRED!!!!!!!!". Those things in my opinion do NOT belong in the megathread.
Hm, point taken. Dodgy situation, can't think of a suitable solution to that right now. Problem is actually, there's only one add-on related, namely the prints on RTB.
Posting images with a pony on it isn't anything worth complaining about.
Depends. I think the few times pictures are really posted, it should at least be related. If someone just posts a pony picture out of the blue, it's the same situation as that WhatTheEff guy. Or Lord loving Tony in the Anime girls thread.
