On the other hand, when I was a teenager, some friends posted content referring to me with pictures on a popular local platform at the time.

I either lost contact with those friends or they lost access to their account, so I tried multiple times to get the platform to remove the content about me, they wouldn't do it, despite all the proofs I could provide them with.

The day I heard that they were finally going out of business was quite a relief.

But contrary to you I made copies of this content, part of it during my attempts to get the platform taking it down...
