I miss the days when it's easy to tell apart spam comments. Gone are the day of good old body part enlarger. Lately, about a third of comment spams look so real that I can't fault Mollom for not catching them. If not for the links to ad farms, there would be no way to tell these are indeed spam.

Take for example this comment made on a page about K2 theme for Drupal.

Thanks for the theme, still trying to learn drupal
