Unfortunately, it's basically impossible to prevent these things, even if I lock things down at home (which I don't want), at school they have (or rather, had) full access to the internet, with little to no supervision. I had a lang talk with the principal about two months ago, explained him what my son was telling about when he came home from school and he was shocked. There were no precautions taken whatsoever. I offered my help voluntarily to setup content filtering etcetera at school, but he immediately hired an external 'professional' company to get things sorted. Which I appreciate, but the fact that the schools network was down for about two weeks, makes me think I might have probably been a better alternative
. At least now, after summer holidays, things are up and running and their possibilities have been limited, which has caused a lot of kids now choose to go play ball outside, instead of playing violent games without supervision. Mission accomplished. At least... for now.
