I have anonymous comments enabled on various nodes.
I have the reCaptcha module installed and enabled.
90% of the spam comments I get contain URL's and special characters (Chinese characters I think).
Is there a way to have Drupal automatically discard these comments that contain the URL's and characters?
I'm assuming the popular Mollom module can probably do this but I'm simply trying to avoid an additional cost for this website.
Other than that, I don't really see a module or a part of Core that offers this feature.
I'm using Drupal 7
