I tried to eBay my legit copy of OS X Server (uninstalled, original full retail software w/original cds, etc. etc.) and they pulled it. It wasn't worth going through the ridiculous process of approval to relist the item, even though I knew it was within my legal right to resell. I even quoted them the applicable portion of the EULA that stated I was permitted to make a one time transfer, etc.. They just don't have the time to deal with individual cases and choose to go the safe route and pull anything disputed. Such a bummer that eBay has become the monolith of online sales and every year keeps getting worse and worse (imo) in terms of quality and safety. I've been on eBay since the late 90's and a few months ago got my first bad deal... bought something and the seller never delivered, trying a classic bait and switch because the item "wasn't available" however I finally got a refund. Just this week I listed a MacBook Pro and I've gotten a handful of third-world morons trying to scam me via international sales, despite the listing clearly stating US delivery only. I'm getting fed up with eBay.
On a positive note, I used craigslist for the first time last week to post a classified ad for a boat. I sold it today, locally, in person, no problem. I wasn't planning on dealing with the eBay BS for something like that (it's not easy to "ship" a boat) but it got me appreciating the quality of a local transaction. Plus, there is the community aspect of it, too. I made a new friend and will likely see them out on the water in my old boat. Alas, I miss it already. 🙁
