Mickeko is right....abuse@ can come in handy, though the first course of action should be at a more informal level. Most people are reasonable, only some are not.
Most times a site will deal with offending works....the only time that falls down is when it is the 'perpetrator's' own site...and he thumbs his nose instead.
Then it's time for having his IP remove the site.
Of course.....language barriers adds to the 'fun'....if you can call it that....
