Thats not the point. OK, you are "sure". I will grabnt you that. Lets assume that is Fact.
What if someone kicks the living shit out of this dude? Where's the proof? Are you and the other boards members prepared for the legal fallout?
What if someone else reads the info and then acts? Do you realize that by providing this accusation, even if you are 100% convinced, that to some extent you are responsible for actions that people may take based upon that info?
What if someone fucks him up so bad that they put him in the hospital? Or, fucks with his car - and he dies? Are you ready for the trail to come back to you?
Dude, I know you are conviced, thats fine. OK, lets say that with NO doubt that the dude your identified IS in FACT the scammer. Now - what if someone takes actions based on that info?
If anything, anything, this should be handled by identifying .... on the board ....
"xyz is a scammer. Don't do business with him. If you happen to live in the Wherever, NJ area, please contact me privately, I would like someone to pay him a visit".
The way it stands now, lets say JohnnyNewbie, a 21 year old ex high school football star on his first Fina/Test cycle, sees this thread, Finds the dude and beats the fuck out of him. He gets hauled into jail .... here comes the FBI calling Elite. Or worse yet, JohnnyNewbie, even though HE has the right info from you, someone fucks up and kicks the shit out of the wrong guy ... but still, he THOUGHT it was the dude you ID'd ....
Its not pretty, any way it adds up.
You are best to let the world know enough data so that no one does business with the dude again. However when it comes to providing personal data that would allow people to find him or his property, in person, then you are taking a tremendous risk.
