It depends on whether or not admins turn the feature on in Features. I turn them off on most of the wikis I'm an admin on because I hate the problems they cause that you suggested, and they're hard to tell between without having to click on their names to their profiles and see if the numbers are different or not. It's annoying. And you can still block them. On another wiki, some of the anonymous users on there say they like having the ability to not have to sign in because it keeps hackers from being able to find them and possibly rape them, which I find to be a bit of a bunch of crap, but whatever.
