I've sold many thousands of $$ worth of stuff on eBay over the years, and you nailed it.

The stupid questions. The bargain hunters. eBay siding with the buyers nearly all the time - no matter how obvious the scam, how new the 'customer' is and how well rated you are as a seller.

Still, there is money to be made there and I have stuff listed. Just haven't been as interested in spending my time listing stuff because of all the issues.
