rlcbm should not be here if he cannot act mature.
Thats how I see it. Its different if he can act mature and not spam random topics and stuff.
To be perfectly honest, despite "spamming random topics and stuff," I'd say Rlcbm is more mature than at least a quarter of the people on these forums. Just because you "spam" or don't chat with great grammar doesn't mean you're not mature. Now if you act like a jerk, troll, or do something along those lines,
that would be immature. And please remember, he's only 12. You cannot rationally expect a 12 year old to talk and act as smart and mature as 15+ year olds online.
