I once sold some parts on eBay from a washing machine I broke up, including the busted motor controller board - this particular model of board was not very sophisticated, but it was difficult to source and very expensive, so I sold it 'for spares or repair', stating that the main triac had blown and taken a track with it, so the board would either need some competent rework, or be stripped for what was still working. The guy whe bought it complained that I had sold a faulty part..and ebay agreed so I had to refund him. I insisted the board was returned 'for inspection' and just binned it. Too much hassle.

Unfortunately even though eBay violated their own written policy by siding with him, this is SOP for them. They have a decades-long unwritten policy of shitting all over their sellers. This became apparent when they removed sellers' ability to leave negative or neutral feedback for buyers, which led to a huge influx of scammy buyers. eBay didn't care because more buyers means more revenue, and the sellers who had built their entire business on eBay had little choice but to stick around for the shafting.
