1) I feel that there are too many unknown in this case, in both the agreement and in usagi's actions. I cannot support giving someone the scammer tag if I'm not 100% sure.
2) I agree with this judgement:
If that part of the deal was fairly assigned value, then I think he should send that part back and be done with it.
The issue with assigning a value to the silence part, would be assuming Bob took it as payment for that in the first place.
Would I have been an observer in the live chat, I would have assumed Usagi was overpaying, and doing so to shut Bob up, but not in the literal sense of a scammer tag, more in the line of, "the customer is always right, heres your refund, get out of my store... I have better things to do" you know, like most retail places will "shut you up" should you be unhappy and loud.
If you really wanted to stick it to him, you could file in small claims court against him. The likelihood of him showing up is small and you could probably get a default judgement in your favor without ever having to argue the details of the contract. But my recommendation, even though you didn't specifically ask it of me... just write it up to a life lesson, refuse his business in the future and move on.
3) It is very clear that usagi has been posting misleading statements. It may not be enough for a scammer tag, but it's pretty damn close.
Neither side in this case has been particularly blamless, but I don't feel that anybody has acted in a manner befitting of a scammer tag. I'd like to give my thanks for all of the people who gave their opinions
I appologize if this post isn't up to my usual standards in it's explaination, but I was highly distracted while writing it. Rest assured, however, that I was not distracted when I made my decision.
Bringing this over to the new page smoothie has so eloquently started.
