I've come to the conclusion eBay is a dodgy outfit. Look how many fake
rechargeable batteries and SD Cards they allow to be sold on
eBay.https://forums.parallax.com/discussion/152959/beware-of-fake-batteries-on-ebay

I tried to report a similar situation where a "buyer" had bid 80% of the
time with the seller. eBay were not interested as the transaction had
ended. How serious are they in trying to stamp out shill bids?
