To clarify
Just to clarify, I do believe there is criminal activity going underway on the part of in31122. I believe civilly, there's certainly breach of contract with respect to the Priceline user agreement. Criminally, in California at least you need to be a licensed travel seller to sell travel, meaning you need to post a bond and meet the licensure criteria. I would assume that this casual user probably is not a licensed travel seller (if they were, I would suspect they would have posted their bond number in their EBay listing, as would be required by law and also by EBay policy). I would also suspect there are some criminal tax implications as this person probably is not submitting occupancy taxes to all the proper jurisdictions.
I reiterate, it was certainly over the top to try to make a case that BFT might be implicated, but undreneath, I think in31122 is certainly carrying on a criminal enterprise along the above lines and I think this is something which threatens the BFT community and the integrity of its data, and in any event, CERTAINLY was/is something worthy of discussion by the members who built the data set.
