I was having the same thoughts. Most of what I've used Archive for is to look up e.g. old blog posts for personalities that show their hypocrisy compared to today, for example. Or someone posted something daft when they were 15 and their handle was leaked and now it's out there forever, and we can laugh at how stupid they were.

I'm sure glad I went to efforts to scrub my personal sites I made when I was a teenager!

I don't think all blogs and personal content(for the lack of a better word) should just be archived. You should need consent. Most people have no idea it's going on. Or it should be very easy to delete something from the archive.
