Dammit! Been away all day and missed all the fun.
So, the OP creates a new account, and his first post is a mildly negative review. He mixes negative with positive comments - so as to make it look more credible.
When the review is questioned, he creates another account, so as to post a fake rebuttal, that's drawn in such obviously over the top language as to be completely unbelievable - maybe in the expectation that we mugginses will think it was written by Ruby herself or a friend, and thus cause her further trouble.
Inevitably, he's rumbled by Admin,

and disappears in a cloud of his own deviousness!
Shouldn't this one be consigned to the fake / malicious reviews bin?
