Looks like you were the victim of someone that didn't have enough time to actually research your complaint.

They checked when the auctions started and made a decision based on that. Not on when the photo was added.

eBay, like many companies, makes a limited number of CSRs deal with so many e-mails in a day that the CSR has to rush through them.

I find that writing another message, but rearranging my words, usually does the trick. For example, make sure the phrase "the copyright-infringing photo was added to listing XYZ on MM/DD/YYYY, 8 days after I posted the same picture" appears at the top of your message.

Good luck.

I hope that this wasn't a case where you were actually harmed.
