User blog comment:Murphy robocop/The amount of underaged people here./@comment-3157150-20151226003656

What you've stated as a course of action (blocking accounts until the user in question turns 13) is exactly the method I put in place if I am able to determine the general time of their birthday. If it comes to it, I will block the account until the end of the relevant year. Users admitting they are under the age of Wikia's stated minimum are already breaking one of the most basic Terms of Use. It is stated on the Community Corner (which can be seen on the side of the Wiki Activity page) that users breaking this policy are subject to admin's discretion as to blocking at all or block length, so this is my personal take on it.

There is no realistic way for us to weed out those who are actually underage without confirming it over time. The other thing to consider is that there are quite a lot of users who like to use the wiki and whose native language is not English, contributing to possible bad grammar and bad spelling. This is the other reason why terrible grammar/spelling is not immediately conducive to a block on the grounds of an underage editor.

tl;dr; we are well aware of the problem, but it is one that realistically can only be dealt with as time goes on.
