I have no idea when it comes to legal, but I believe it would be wise to add a disclaimer that users are solely responsible for the data uploaded, etc etc.

I remember a similar previous discussion but I can't find it. IRC it's not so easy. If they don't make something, they can get in trouble in spite of the disclaimers.

Thanks, I fixed it. Realistically lvl would never go above 3 digits, but in theory all cases should be covered, absolutely.

Well, you see my point now :)

I made three different algorithms dealing with spamming messages, spamming reports (repoting people unfairly), and when to ban someone depending on the reports gotten.

Contrary to most sites which do nothing (as to get the traffic from the trolls anyway), if someone is being intrusive, I ban him for a limited time, or the after two times, permanentely.
