I might be wrong but I think might be misremembering something, Myspace lost all it’s user data but not till like 2016 which was years after news corp sold the site.
They didn’t delete the users, but they deleted everyone’s blog posts, and i think wall posts and settings too. It has been decades now, but I remember a bunch of content disappearing right after they bought it, which drove more people to check out Facebook. Then later I think they wiped the pictures from people who hadn’t been active in awhile. I know at some point all of my pictures disappeared, and that’s when I finally completely gave up on the site.
