Hi Socks, I own Carnalia.com and was recently in a similar situation. A webmaster was accusing a site that I had reviewed of stealing their content and using underage models. I naively wasted heaps of time attempting to mediate only to have one of them (the site being accused of mischief) turn around and start accusing me of harassing him (ie by asking if the accusations were correct).
So my advice is to either ignore them and keep the reviews as they were before the issues were raised, or delete both sites. Under no circumstances should you get involved in the debate as you'll waste a lot of time and probably end-up caught in the cross fire.
