Avoid Linkback Abuse (ALA)

Some commentors try to abuse the WordPress Comment’s built in URL feature by submitting advertising, spam, or otherwise unwanted links.

Avoid Linkback Abuse tries to prevent this by providing two different modes of operation:

• Strip all anchors from comment author’s names as they appear in the comments list at the end of posts (always on when the plugin is activated).
  • In addition to the above, this mode will remove entirely the ability for commentors to leave a URL. Assuming you’re using the default WP Comments plugin without any additional comment-modifying plugins, this mode still allows commentors to leave their name and email.
