I draw during boring lectures, lunch, and other free time. :3
I'd prolly get in trouble if school teachers saw what I wrote, too...
Iunno what people have gotten expelled for at my school... one overacheiving smartypants kid I sorta know was suspended for a bit for breaking into the school wireless network and messing around on the school computers. He didn't do anything all that bad though, mostly just writing snark comments (Ex. "Shouldn't you be doing SCHOOLWORK?") where the website url goes. (I should know, I used one of the comps he messed with.)
Oh, and "noneducational" websites get banned from the school blocker thing all the time. As of today, Gaia, Myspace, Tektek, Subeta, Penny Arcade, and Addicting Games are all blocked from school comps. dA's accessible, though.
