@Glen took care of the scammer -- many thanks to him as I was out at an appointment this morning. Evidently he was quite prolific; in the space of about 75 minutes, he sent somewhere north of 20 private messages to people attempting to scam them.
For good measure, I referred this particular case over to
@The Emperor for a "force-choke" to ensure that this individual is taken care of, permanently.
In any case, he was despatched quickly. But, of course, he'll be back under another name/email address. They always come back.
It is heartening to see that most folks here are now wise to this scam, whereby someone newly registered to the forum sends a DM to a member and refers them to a "friend" at another e-mail address (usually a hotmail address) that supposedly has the part for sale.
This scam is starting to actually, get quite old.
I'm sure another scam style will surface in the near future.
Again, the best thing you can do when approached by someone here, is to look at when they registered for the forum. If newly registered and they have no posts publicly, it's cause for extreme suspicion. ONLY deal with well-established members here with a track record of many posts, and perhaps even past parts for sale.
It's easy for all members to do a quick check on any other member's profile.
