Very simple; newbies dont read anything, specially NOT the Newbie Guide or the Information section.
When they do, and when they are under 18, they try to find every possible loophole. Then they get pissy about it, cry about maturity, etc.
We see that almost every day, it never stops.
The only solution would be to lock these forums to a Read Only status until age-verified (with options for out of country members). Then they would have no choice but to read and learn.
