FemScat offers DMCA takedown requests done for your content as well as Google search result scrubbing for sites that don't respond to DMCA takedowns.
Submitting these requests yourself requires you to use your full legal name and address so many models don't want to. As the owner of FemScat, I am happy to use my legal information in your place but I can only do so for videos that you have listed for sale on the site.
For my own content I am usually successful half the time getting things fully removed, and can always get them to not show up in google results the rest of the time.
I hope this helps!
