I remember (vaguely) pinging AOL's irc servers with hays cmdset commands and as a result my parents getting a letter to the effect that I was a computer criminal and we were on some 'blacklist' forever, fortunately this apparently blacklist didn't seem to be shared between ISPs so I was back causing chaos within days >_<
And now here I am, mid thirties, children, and I wonder if I would let my kid play DOOM when he is 8 or 9.. I think I'll let him play the original ones, but the newer games seem to be much more intense (maybe that's just down to the graphics/music?)..
Or I just let him play everything.. I dunno, grand theft auto (granted, the top down one) did me no harm when I was around puberty heh...
