COPPA says that no one under 13 can give out personal info online. Wikipedia says that, although kids registering for things isn't illegal, many sites (like Wikia) disallow it altogether because of the paperwork involved. (Though if I ran Wikia and had no choice but to disallow it, it would be because kids are kids and are very inclined to break rules and let something slip.)
