UPI Negs: the Clean, the Dirty, and the Gray

Will UPI negs always be removed?

Generally, if seller files the UPI dispute, and closes the dispute with high bidder receiving a strike, any neg that bidder leaves will be removed, albeit with some perseverance.

That leaves the analysis of the "generally". Why not "all"?

To keep score, one first has to separate UPI negs into "clean cases", "dirty cases", and "gray cases".

Clean cases are when high bidder, either in communication or not, simply refuses to pay.

Dirty cases involve seller giving buyer a reason not to pay. Yes, bidder can appeal the strike in such cases, and negs will re-appear or a new neg can be left.

Gray cases are when some reason is claimed by buyer, but it's not clear how, or if, seller participated in that reasoning.

We can't mix them up, because ebay has no problem with dirty cases ending up with a seller neg.

Clean cases sometimes require more work than one might think would be necessary, but they always end up with no neg when seller persists.

Gray cases, are, gray.

I do know of one case which seller claims clean, but the neg stands. I have no explanation, but I know of 100+ cases where the neg was removed, so I don't take the one as being other than an outlier.

The opaque nature of appealing a UPI strike also prevents understanding a concise statement of ebay behavior. Strikes are not publicly visible, nor are appeals thereof.
