kicked off the bay
since i used to fly around a fair amount, i was able to earn some southwest reward vouchers. the neat thing about southwest reward vouchers is that they are fully transferable, meaning you can sell it to other people. since i had a voucher that was pretty close to expiring, i decided to try selling it on ebay. a quick search for comparable items on ebay revealed that ebay would not allow the sale of such items. instead, people sold white envelopes and gave the winner a free reward voucher as a gift. so i proceeded to list a white envelope for sale, along with a reward voucher as a gift.
a scant 5 hours later, i checked my email to find a kind letter from the authorities at ebay informing me that my listing was removed due to a prohibited link to a website (southwest.com). there was no link in my item posting, so i can only assume that they real reason was that they objected to the free gift i offered with my item. interestingly enough, in the 5 hours that my item was available, i received two emails from people saying they would be willing to purchase my "white envelope" in the (apparently likely) event that ebay took my listing down. and i was ultimately able to sell my voucher via these means.
so the moral of the story is: even if you aren't allowed to sell stuff on ebay, you can still sell stuff on ebay.
