I thought that BB3 would do nothing extra for me.

It will, the image captcha system is much improved. The one on phpbb2 is all but uesless. For stopping it on phpbb2 you need to istall spam mod, there's long thread on phpbb2 here:

[phpbb.com...]

Installing any of the mods that require the registrant answer a text question will stop them dead.

What forum system to people use to "authorise" registrants, the type that e-mails you with a link to confirm regsitration? Would that help?

Both phpbb2 and phhbb3 have this option, Nor sure how much it helps as they have numerous email addresses they can utilize.
