I talked to the webmaster at our school and he suggested that I visit the police website, they have a special section where one can report illegal websites and hacking. So I just did. One can do it all on the computer, so it wasn't scary at all. It said I can't expect to get any feedback on where the case is going but to leave my phone number incase they needed more information, so I did.
I realy hope they find the people who did this. At least now I have reported it, so I feel a little better about it, even if I never know if they are found.
I didn't know the police had a special section for these things. It specifically said that one could report websites with child porn so maybe they can do something about it.
Thank you all for the help, I'll keep you updated if I hear anything.
