Catharina- This just an idea, but I've had several friends who have had the same problem of original content being pirated and given away. Now, anything you create has an automatic copyright to yoy as the creator. Simply reporting the offending person to their service provider, with a link to the original content (for verification of ownership), is usually enough to prove violation of their terms of service. (99% of hosts have that provision.) This is usually enough to get the offender's website shut down. I have done it several times, myself, so it does work.
