Ageism to a degree is fine. I don't want a 89 year old flying my plane, and I don't want a 14 year old deciding how to interpret the TOS. I'm comfortable to see 16 year olds modding, but below that very few are mature enough not to abuse their power. Not to say there aren't 15 or 14 year olds who can be good mods (we have a few on IGN who are fine), but most aren't.
