There are already some sites where you're much better off if you have an old account. Like I have a super old Twitter sitting there for random stuff that requires it. I tried making a new one a few years ago, didn't post anything, and it got banned within 2 days for "bot activity." The old one has never been banned.

It was also so much easier to make a dating app profile back when I was single, like one click. Recently was watching a friend set one up, and now they not only want like 3FA but also proof that you're a human. Assuming the old accounts are grandfathered in.
