Let’s say you buy a few coins on eBay . Let’s say you get a fair price. Let’s say when the coins arrive, though, they’re packed poorly, loose in an envelope. Not good for old coins.
So, because the price was fair but the shipping sucked, so you leave neutral feedback. That sounds reasonable.
But let’s say the seller then sues you for $10,000. That’s the story of Steve Shellhorn. That exact scenario happened to Shellhorn, and it cost him $500 to hire a lawyer to convince a judge to drop the suit.
Sadly, the fiasco has put him off leaving feedback ever again, an important part of the eBay system. The seller is mum, but we’re guessing he feels “Great buyer would sell again++++++”.
