The idea is that if they volunteer the information, you tell them "for your own safety, you shouldn't tell people what your age is when you're online" and try to let the matter drop. If they ask why, point them to the "Personal information" section Chat behavior and guidelines.

What we don't want to do is to ask people what their age is with the intent of kicking them out of the chat room if they're under 13. Technically, that could be a violation of Wikia's Terms of Use (ToU). Not just for the person who is under 13, but for the person asking the question.

According to the ToU, you are not allowed to ask someone who is under 18 for any personal information. I think their thinking is that if you find out someone is under 18 and you keep asking them personal questions, you're going too far and you might not have good intentions for getting that information (in other words, being a predator). Your age is part of your personal information, so if you happen to be under 18 and someone asks you what your age is, that's where technically asking the question could be a ToU violation.

In short, whenever possible, treat someone being under 13 as a mistake if it becomes known and don't use that to punish them by kicking them out of the chat. If you try to get them to drop the subject and they won't, then a kick or a ban would be appropriate.
