I believe there are acclaim mod/VGM that look through the ebay listings, that file reports of copy right infringement. All it takes is a simple report to get the listing removed.
I posted up my hunter a month or 2 ago and had the same issue. luckily, i had people PM me through ebay asking to buy it :D So I eventually sold it for 500+
I actually think, that it was my hunter that cause the whole commotion of selling accounts LOL... I even had topics on the main forum about my account being on sale, i won't say my original IGN though ^^
My advice would be... setup 1 day auctions or setup a fair buy it now price. Just sell them fast, before those MOFOs get them removed :cool:
