Why do people use nicknames instead of saying “ebay”?
This isn’t just a joke – although some funny versions certainly do get used! – it’s all about preventing ebay google ad’s being displayed on eBid’s site, and preventing the references from being counted as “popularity” ratings for eBay. It’s a matter of personal preference, but you will probably irritate some regulars if you don’t avoid using the real name. I sell in both places, so feel less strongly than some, but do follow the convention for the sake of politeness… your choice!
