I'm actually confirming it was a DMCA request. I might have jumped to that conclusion and it may have been something else just trying to extort money from her. I'll update once I find out.
So I was wrong when I said it was a DMCA request. It was actually Getty images telling her she was using an image without licensing it. When she asked which image they sent her a link to the rip-off site since they assumed it's her. Now she just needs to tell them it's not her site and she'd be glad to have them issue a DMCA request.
