The flip side of this issue is that protecting UGC sites is that false claims can persist despite reasonable efforts to correct or remove them. This can create reputation management issues for legitimate businesses who have been maligned by competitors or just plain wackos.

While a good site operator will check claims of bogus posts and remove those that don't appear to be legitimate, plenty of other sites do nothing or will extort hefty sums from the victims.
