Honestly, on many official sites, there are age limits of 13. Even on Youtube, which is an actual business thing and deals with the law! So if a website like that has an age limit, we should too.

Yes, I understand that people under 13 can be mature, but still, a lot of people have proved otherwise, aha. :P
