Topic: Forum rules - what should be there to prevent legal trouble?
Most forums on the web have a huge page of legalese describing all the rights, responsibilities, and duties of those who contribute to the forum. The punbb forum is an exception to this rule with the one-liner "Don't post anything you wouldn't want your mother to see.".
In an ideal world, that should be more than enough, as the moderators weed out the inappropriate posts. However, in reality angry users might resort to legal threats. I read in the Swedish forum about a guy who was threatened to be sued for not complying to the Swedish privacy law which requires explicit consent in order to store personally identifiable information. (It seems to me that it's pretty clear that information will be stored if you fill out an online registration form, but who am I?). I can imagine hairy copyright issues if the forum posts are moved to another website at some point in the future, and so on.
So what is the minimum ruleset that will cover me legally for this kind of things? For the record, my site is in Europe (Netherlands).
