Use a free anti spam plugin or a premium plugin like http://www.q2apro.com/plugins/stop-spam It also blocks parts of domains and URLs if you specify them in the options.

I have wrote a blog post Basic anti-spam configuration for Question2Answer:

  • change default text strings, which attract manual spamers
  • install "Install Very Simple Bot Protection" and create custom anti-spam questions
  • deter Semalt using .htaccess.

More details are in post.
