OK, I'm a little lost here.
An anonymous poster puts up a complete unsubstantiated story on backpage defaming MJ and Nikki. MJ and Nikki post this isn't true. I don't think I read a SINGLE questioning of the story's source, not one. We have a couple of dozen posts belittling members of community, whose reputations have been attacked by what is almost certainly a false story (if it was true, it would include some sort of citation.)
Doesn't seem all that productive if you ask me. I want to know who posted the story, let that little coward come out for this treatment. In the meantime, we have a fallacy going and MJ and Nikki are being asked to prove a negative (prove that you don't is always a difficult argument. It's like, "Oh yeah, prove you're not gay" or "Prove you're really broke" or whatever. Any defense comes off sounding like a lie or cover up.
Personally, I like to check my facts before I speak on a subject.
