Should eBay choose to pursue this and you choose to defend it, you may make a good case. I'm not sure if your site has anything to do with auctions, as I can't reach your site ATM - I'm guessing you've been slashdotted. You may argue that you do not share any similarity to eBay and "bay" is a common word.
Right or not however, changing your domain could be the easiest course of action. Especially if you're not attached to it yet.
