But I saw nothing in that article that indicates "scam". A website receiving money but not delivering the item (regardless of what that item is) can so easily be more about faulty code or a faulty payment system on that site. If anything, this means that something somewhere got stuck and in the case of these firearm sales - that's a good thing.
Read the article(s) again.
Their primary venues were online forums and "market places" (inferred to be Armslist, Gunbroker, and local classifieds like Utah Gun Exchange, Phoenix Gun Trader, etc.), and their targets were private sellers -
not FFLs.
There's no "website glitch" that stops a money order or personal check.
A person doesn't need to be internet savvy or computer savvy to scam the old fashion way, either (failing to deliver the goods).
Even though essentially irrelevant to this topic, I still don't believe that monetary transfers run into 'glitches' and 'getting stuck' on a regular basis - especially with actual online retailers (with FFLs).
Scams from private individuals happen all the time, though. That, I would agree with.
Three cases in point, that I have been involved with:
About three months ago, a member on MarlinOwners contacted me to find out why I was selling his rifle again (I had purchased it from him last year). Except... I wasn't. Some one had snagged the "before" photos from my project thread and listed the rifle for sale on Armslist ... under four accounts and in four different states.
Less than a week later, that same member sent me a few photos, asking whether or not I thought a rare (original) Marlin 1895 take-down in .40-65 was priced right, after he negotiated with the 'seller'. I replied with two screenshots of the same rifle listed in my area, on two separate classifieds sites, with totally different contact information; and then, after some searching, followed up with a link to a legitimate 'firearms collectors' auction site where the rifle was
actually listed and had un-cropped photos with watermarks.
And, if we go back about two years... I get an angry phone call one day, from a man whom I had sold a non-running car. He was ranting and raving about how I'd be "sold bold" as to sell him the car, wait for him to give up and scrap it, buy it back (150 miles away, mind you), and list it for sale again. Except, again, I hadn't done so. Some one had copied the original listing, almost word-for-word, used the same photos, and used my name and phone number; but created the listing with their own email address.
The funny thing about that one is that when I reported the listing to the site administrators, they ended up accidentally reactivating my old listing while deleting the scam ... which didn't look so great for me, from the perspective of "Angry Man"...
