Actually, people tend to think I'm older so I'm technically not discriminated by my age. ;P Besides, I wouldn't ban anybody without a good reason.
The original poster was probably disappointed by how we derailed the topic. Either that or he got scared off by our general strangeness.
Personally, I think age is irrelevant on the internet. Maturity is all that matters. If there's a 17 year old typing like "hi u suck i haet u i bang ur mom lol," he might as well be 5, and vice versa.
