My main hope is that it will be clear from the page's history that I've been involved from the very start, and the new "owner's" actions will look as suspicious to a real human as they do to me!
In the meantime, I've updated my blog to mention this discussion, proving at least the blog part of my ownership :)

(hopefully, this, and the fact that the now deleted page used to point to this page for the last 10 years should be enough!)
The person who has taken ownership would have different machine fingerprint info.
So Facebook should be able to confirm you have been the main uploader for quite some time.
I have nothing to gain from a PR stunt. As you can see from my website, it's a small blog, not a mainstream professional website. But it means a lot to me sentimentally, because it's something I have been working on for 11 years, and a small (well, 56k small) community of metalheads was built around it. The last few years the only content was the end of year lists, but this was very popular on Facebook.
I think the main reason it became valued among metalheads is because it's not a "mainstream" list, of the kind promoted by the music industry, every year the same people... I go to great lengths to find out great music. Often enough, a band which I think deserves to be on the top 20 list may be relatively unknown in mainstream media, and both the bands and fans seem to find value in this and thank me for it.
Check out the end-of-year list for 2021. You may find something you like. I particularly recommend the top ranked album on that list, Thy Catafalque!
