We also had a problem like this at the middle school 4 years ago. My daughter went to see why everyone was huddled around a computer, and the kids were looking at PORN!

Back then, I contacted the principal, and she said that they didn't belive in "censoring the internet" so they didn't even have a safe search on the computers. In the next school newsletter, she even wrote an article regarding her position on why they don't use any type of safe filters on their computers.

That was in the same school district, so I bet they don't have any filters on the computers at the high school either.
