Especially if you’re a corrupt politician, child abuser etc. it’s really helpful for that sort of people. Not so much for everyone else, but why would that ever be an issue?
I would think that, especially in a everything-online world, this is very useful for regular people. I for sure have removed some links to embarrassing posts I made as a teen, to which I've long lost account access to, to remove manually. And now with everybody's kids being on Tik Tok etc since very early age, I assume it will be used more and more.
