That may be DMCA notice but I think that BluGill get to the heart of the matter in saying the Google doesn't follow the DMCA process. They have their own process that is a warped mirror of the DMCA process and they use the DMCA process as a fig leaf to hide their policies are different.

Google was notorious for not acting on counter-claims: "For anyone out there who have been DMCA'd from Google and a properly filled out counter DMCA to them was rejected with the following: "Thanks for reaching out to us. At this time, Google has decided not to take action." Please contact me immediately " https://x.com/gelbooru/status/1168036119893688320

Here is a January 2026 view for the pro-easy take down side showing that Google is now requiring identities to issue DMCA claims: >"Fast‑forward to January 2026, and the same system now questions the very identity of the complainant, demanding proof that was never required before.

I don't know how to tell the difference. Google has incentive to hide this
