these happen a lot. I signed up for my username on ebay with a yahoo account. In all my ads, I give a gmail account. You would not believe how many emails I get, in my gmail account, from "ebay." I know they'll send me anything important to the address I gave them, and anything in my other account is fake. Oh, and gmail does an excellent job of sending all of these fake emails straight to spam.
