would it be a good things for captchas to be useless? Because in my career I've been a few times on the receiving end of spam attacks and various nastiness and it's nice to be able to integrate such a thing - as unpleasant as it is for the user - and solve the problem at hand. if this disappears then spammers and the various botnets will have the upper hand again.
