trying to understand...
you pick the 500.
if you find a case, then bring it to them, and they do all the emailing to the offender, settlement negotiations, etc., correct?
You still have to do the Reverse image search, correct? (not a deal breaker, I am just trying to understand.)
No, they do that for you. You essentially give them the image to search for and they take care of it.
You can upload images and they will do the reverse image search for you on a certain number of images and you can pay for a membership for more. At least, that's how it was when I got started, but that was a couple of years ago, now.
I found mine by reverse image search on my own, however.
