Hate to double post but we have people called "mods" who most seem to have forgot when writing your responses, any annoying 7 year olds will probably get a ban, then move onto another site to spam, like sumat that deserves it like eBaumsWorld.
That and i think 7 year old don't have the capacity to be total jerks over the Internet, it around 10 years old when they start developing major egos that it occurs. Most of the kids in the youngest year of my school will talk trash to us in 6th form to make themselves seem "hard" and "cool".
I recently went to my local primary to help out for extra credit, and the first thing that hits you is how polite they are, could be the fact they instantly think your cool cos your 17 or they just don't have the capability to be real jerks but i have respect for kids that age, there just so polite you can't hate them.
Then they grow up. Shame.
