Even if there were age requirements to post, you'd still have someone underage posting. They just lie about their birthdates if they want to join a site enough. A friend of mine told me about a teenage forum site that her son frequents, now he is the correct age to join, but we viewed the site and recognized many, many posters who we know are under the age 16 limit. Some of these kids didn't post their age as 16 but some as old as 40

Hmmmm, some sure are aging well, cause their pictures look like a 12 yr old kid. Kinda funny. I guess the moderator on that site isn't paying a whole lot of attention
School's out, let the fun begin cause there's a definite increase once they're home with nothing better to do....
