That is the lazy clearnet idea that IP bans are the only way to block jerks. As I've pointed out numerous times, effective moderation can be accomplished through a combination of privilege and work factor systems. The Newbie board is an example of a privilege system, where you need to build a reputation to earn certain privileges. Unfortunately, it was done hastily and incompletely. You can spam your way to 50 posts in under an hour. A better system would incorporate time requirements, such as 10 minutes between posts and/or 10 logged in hours on the forum and/or account promotion after 7 days. An even better system would take advantage of the existing Karma feature that currently has no purpose other than vanity. A work factor makes certain actions like posting or account creation more difficult. The captchas are an example of a work factor, but they are clearly not enough. On clearnet you can slow account creation by requiring an email address. Even better, require a Gmail address which turns the problem of mass account creation over to the skilled spam fighters at Google. We don't have that luxury since we need anonymity, but there are ways to add work factors to account creation here too (eg, decryption of a PGP encrypted code). The point is that there are all kinds of things the admins could do to work smarter rather than making their mods work harder.
