That is a scenario. Consider an alternate scenario:
Player A dupes 50 barbed kits.
Player A splits them into stacks of ten and distributes them to trusted accounts (different billing and IPs) B,C,D,E,F.
Those accounts now put the kits up for sale and collect the profits, routing them to account G.
This is a terribly common setup. How do we, as a company, distinguish between your scenario and mine? Between the unwitting patsies and the knowing collaborators, or the shell accounts with spoofed IPs?
Okay, you need to clarify this then:
Did you track these items through their progression?
IE: Player A created and gave to Player B, C, D, E, F?
Or Player A SOLD to Player B, C, D, E, F?
And Players B, C, D, E, F were each actively SELLING these items?
Or Players B, C, D, E, F were in POSSESSION of these items?
And then Player B, C, D, E, F transfered funds to Player G?
Or you're presuming that's what happened?
Because right now, it seems like you guys have put a lot of guesswork into this, and not a lot of actual solid anything.
Short answer is, we cannot determine intent. We have to go on data and numbers. It's not perfect - it'll never be perfect - but it's what we have.
Then what you have is a system that can ban innocent players based solely on number items alone, without showing any history of what actually happened to those items. If you're truly tracking them, you should have a trail for each item. I somehow doubt you are though.
(And come on, folks - the vendor with 30 val hammers? Or the one with a single one, for cheap, that never seems to run out of stock? DON'T BUY THOSE.)
I'm sorry, but you're asking us players to make determinations as to what is and is not duped, and that's absolutely ridiculous. If you're going to continue to make player vendors available, and you're going to continue to allow players to make purchases, then you cannot hold players responsible for WHAT they purchase simply because you think we should all know whether or not they're duped.
If I purchased a valorite hammer from a vendor once a week for five weeks, it sounds like it'd be enough to ban me. You're presuming that I know what market average is, that I would know whether or not it's possible to get more than one valorite hammer in a week through BOD playing (especially considering the current methods for getting BODs in play), and that I'd have stopped back multiple times in a week, noticed how quickly they were being replenished, et cetera. Or that I happen to read every thread on a message board.
I'm unlikely to be affected by this simply by virtue of what I happen to do in game, and the fact that I rarely spend money on stuff -- except that since I have a museum that has community rares in it (thank god most of them have been given to me or I have actually earned them myself), and should I happen to buy one too many that was somehow duped, and I didn't think to myself, "Wow, that's got to be duped," that I might someday find myself on the end of a ban stick really makes me want to beat you to the punch.
You've essentially begun the Salem witch hunt in UO, and you're using carrot noses tied around the faces of some folks as an excuse to burn them. Meanwhile, some duper standing around is shouting, "Well, I did the nose, but she's still a witch!"
