Mark, i had decided to leave you alone but i'm going to report you to all the Listia Moderators I can... good luck, you're going to need it.
to anyone curious about this dispute, MarksJustGaming sells FREE BING SHIRT avatar items to people for 400-4000 credits and calls them "xboy mystery codes" he's also clever enough to post in his feedback to them "ENJOY YOUR 1600 MSP CODE!" and then he blocks the buyer, leaving them confused....
