ebay has a keyword spamming rule. its been active since august or something.
if you are selling a list or a guide or anything thats not really a wii, you cant put the keyword wii in the title. (goes for everything really, ipod, ps3, ambilight tv)
so if people search for a wii, they wont get a wii list, guide or some other shit they can mistake for a real console in the search results..
just read ebay tos.
its done for the wholesale lists everyone was buying, expecting a real wii in the mail.
