Well, I can offer a few thoughts from a board perspective.
1. It is ok, and preferred, to out someone that has scammed on the board. That being said you better be real sure of what you are saying. You are legally liable for anything you say on this board. (I am not liable for what anyone else says but am liable for what I say

)
2. It is not ok to post addresses or phone numbers or other confidential contact information, except with the approval of the other party OR if it is an extremely obvious scam. Then I/we would love to see as much info posted as possible. That is extreme and rarely happens. I think it happened most recently in the Edwin Arroyo case. He is a well know thief and his info is not protected at all. I can say he is a well known thief as I have emails from him admitting to it. I think he, and his cohorts, days are numbered too

. I have nixed out the exact addresses on the envelope above and part of the confirmation numbers. They did match.
3. On the subject at hand I can't really tell who is right and who is wrong at the moment. I am sure it will be clear soon. This board is like a snapping turtle when it bites something.
4. It is worth mentioning that there is a "caveat emptor" premise on this board. Besides normal legal channels the only thing I, or any moderator could do (if warranted), is ban someone from the board.
