Tangent but reddit allows people to hide their post/comment history which is fine I guess but it's not great for that reason, trying to see if an account is a bot or not. Other than age can't tell anything about that account.

I notice more and more accounts use it, particularly the spicy commenters. Which is whatever, I try to stay away from social media now, this is SM here but at least it's more technically oriented/useful.

People can curate their profiles, but not search results. Their posts and comments will still show up if you just search on their user page.
