>Suppose that in order to post on the site, you first had to register a username and password using a unique e-mail address. We could even build in a delay of, say, 24 hours to the registration
So inviting evaders to farm accounts to not even bother resetting their rooter?
I believe the main problem is trying to prevent ban evading. Once a user is banned, it's their choice if they want to respect the moderation or just continue posting, and there is nothing we can do to prevent this. It's simply pointless to police over users for ban evading unless they are a known problematic dude or openly admitting evading.

This can be controversial, but I think 4chan's appeal to many people isn't only the anonymity, but also the ease of use that comes by not having to fill a form to "sign up". I personally, would rather post with some kind of tripcode I can't rid of that would identify me over threads instead of posting anonymously with an "account".
