Heh, we're talking about the USA, people here sue over anything & everything. All it takes is for someone to be morally offended or catch their kiddies on the internet seeing a boob or two to get the court ball rolling.....things that seem trivial in other countries are or can be a big deal here.
In any case, mature content filters would be a good idea as many view from work & the ever protective parents trying to keep their kiddies from seeing a big boobed nude Vicky all nipped out.....:/
