Barricade
Barricade is an extension for ExpressionEngine 2.x that queries the http://stopforumspam.com database for each member registration. If a match is found for either the member email or both the username and IP address then that member is immediately moved into the Banned member group. It also logs this action into the CP log.
Accessible Captcha for ExpressionEngine 2.x
This extension changes the default graphic captchas to user-definable questions and answers. The settings allow you to create any number of simple questions and answers that will be randomly chosen in place of the captcha. These captchas are completely accessible as long as you remember to make the questions straightforward and without cultural context (unless you need to restrict usage to a specific group or type of site visitor).
Acessible Captcha works everywhere that the default captcha would work i.e. on member registration and comment forms etc.
This version is completely compatible with the ExpressionEngine Multi Site Mananger. You can create distinct Q&A pairs for each site.
Restrict Entries To Member Groups
This extension enables another tab in the Publish page (configurable by weblog) that allows you to restrict that entry to certain member groups including the Guest group (anonymous site visitors).
It was originally conceived as a more robust way of ‘sandboxing’ content rather than either creating separate templates or defining member group/status conditionals within the main templates.

Accessible Captcha
This extension changes the captchas from graphic words to user-definable questions and answers. The settings allow you to create up to 8 simple questions and answers that will be randomly chosen in place of the captcha. These captchas are completely accessible as long as you remember to make the questions straightforward and without cultural context (unless you need to restrict usage to a specific group or type of site visitor).
We have tested it (and are using it successfully) on the member registration form to reduce the number of automated signups to ExpressionEngine Sites. If profile linkspam is becoming a problem for you then we would also suggest you have a look at Member Utilities
