In my experience, no they won’t help with gdpr takedowns. The only way to make things unavailable is actually to file a dmca notice against any url that you want hidden. This was actually the recommended approach from GitHub when I asked them about this. Absurd.

I would have expected that I could say "This is my code, hence this is my data, and I want you to remove my data from your website". I wonder how hard it is to file a complaint to the EU and see what happens.
