I think this has been asked elsewhere before.. but I got a more specific question... Since we sell VPS and allow people to install their own scripts on the machine, how do we know that they not put something illegal on? Short of checking their content constantly?

The reason I am asking this question is that with the rise of "social network" scripts, anyone can buy a $200 script and have a VPS then close the membership to invitation only.. how do I know that what they put on my server is legal pictures etc? Sure i have got TOC etc but I don't want to be the last one to know until the Police come knocking on my door and asking who the customer is...

so any collective wisdom is much appreciated.
