For all of the weight that it carries, I'm with Lew on this ...
Name .... OK
City/State ... OK
Phone ... Not so much
StreetAddress... Not so much
Having said that, if this guy were a criminal scammer, I would think differently.
We have a guy, relatively local to me, who is a well-known scammer (search: Mark Uttley) on RGP, CL, KIJIJI, Mr Pinball, CGCC, MAACA and other sites. In that case, where there are CRIMINAL charges involved, then I can agree with the release of personal information for confirmation of identity. NOT because some 18 year old kid on a message board says so (and I believe HD's story, but really, what do we know about each other ?).
Oddlly enough, I was talking to a friend of mine at Saturday's auction ... he matches the general description of the local scammer, drives the same freaking vehicle and lives in the same general area ... yet, he is completely legit and unrelated to the scammer (confirmed, though I tease him otherwise). Sucks to be him right now. (neither here nor there, but interesting consequence of the release of information).
