1. Yeah, not a fan of doing this. I’d rather use a captcha or just stick with Akismet, to combat spam.

    Akismet does a dang good job, in my opinion.

  2. Those long comments with all the links are posted by spam scripts and won’t be affected by any javascript in the comment form.

  3. JavaScript won’t have any effect on spam. Bots generally don’t process JavaScript. That’s why captcha’s which make use of JavaScript are very effective at blocking bots.
