Well. Let me put it like this. We already had few amazing adventures involving such safe content and some people who seem a bit overattached to the conception of My Little Pony as the ultimate utopia and in fact the only good thing they ever had in life. The results were however pretty much the same every time. Wild flamewars engulfing half of the forum and people throwing tantrums everywhere so since that glorious time, this particular community prefers some extra caution when dealing with content that possess the fabled ability to rustle some jimmies. Or if nothing else, at least tag it if not sure. Most things (if they are not too horrible) can pass pretty safely if you [tag] them and encase them in the spoiler button.
