AI channel plagiarised one of my videos

A smaller channel which is full of plagiarised AI voice over videos taken from other channels took a liking to my work, and plagiarised one of my videos. I asked him to delete it inmediately, but he just shadowbaneed my comment and others calling him out.

In my video i talk about mechanical parts for around 18 minutes, i think he just downloaded subtitles and ran them through an AI Voice and changed like 3% of the words and some stock footage as background, everything else is an exact copy of my video.

So i made a copyright infringement claim or however is called ( reclamación por infracción de derechos de autor de YouTube)

Is this going to work? it made me really angry, i also notified many other channels about it so i guess they must be doing this or something else.

What was your experience with this?
