And you can't even do that unless you've already managed to remove the image from the internet:

If they do they are in "deep shit" (pardon my french) legally. I actually hope they do this - and somebody can catch them in the act. I believe they will be gone soon then.
Also I would advise anyone under GDPR legislation to also request exactly with whom the data was shared and go on to also request deletion and usage information from them. It is a pain that one has to jump all these hoops. I would love for the GDPR to have a way of forcing such a company to also do the information and deletion requests on your behalf and prove that to you.
Sadly this was not included I believe.
So, I get why they ask for ID, even though I also get the reluctance to give them your ID since it could help tune their system.
