You joke, but this is a real concern for me ... even if I do get a person replying here, presumably the hacker used dodgy means of getting access in the first place! how can I definitively prove what I'm saying is true?

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!)

I'd assume Facebook has been tracking IP addresses and other computer fingerprint info from the machine(s) you have been using to upload content.

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.
