Lately some folks got into habit of creating trackback links pointing to my website from porn-related sources to de-index my site. They succeeded to a sertain extent, but I managed to spot them through GA and now I'm blocking their websites through .htaccess. The procedure is painful and I decided to ask you, good fellows, if you know how to block trackback links as they appear before it becomes a problem. I know WP has some protection from backtrack spam, but I am not familliar with the mechanism.

Spam is a well-known problem with Trackback and Pingback.
Possible measures against the spam:
- Fetch the source and check if it really links to you
- Pipe the request through a spam-analyzing service like Akismet
- Pipe the source site content through a spam-analyzing service
- Have a whitelist of people you know and trust, and block the rest. This isn't that nice for people you don't know and that send valid pingbacks.
