I have a site using Drupal as CMS, and got infected badly with spammer bots.Moreover, recently I signed up for Google's Webmaster Tools, and I see that one of the top search queries that result in my site is more information about text formatsAnd I know that this block of text appears in drupal sites.So I'm guessing that this is the bots' way to find spammable drupal sites. So is there a precaution for this? I already made robots.txt to Disallow: /drupal-subfolder/ but apparently this does not affect malicious bots.
