New ebay payments require SS#?

I received an email from ebay and they now will deposit your amount from a sale directly into your bank account.  So, they require your routing and account numbers.  But they also required my SS number, which I'm not sure I like.  They say the purpose is to comply with government regulations.  Is there any reason to think they would transmit the amount of your sales to the irs and issue you a 1099?  I only occasionally sell used items on ebay and don't consider any amount I receive to be taxable income.  Thoughts?
