Basic Antispam Plugin ~ readme / help file

Big Picture

This plugin provides basic methods to detect & block spam on referers, comments & trackbacks.

Settings, Settings, & Settings

Plugin Settings:
  • Allow anonymous comments: If checked, unregistered visitors will be allowed to leave comments (which increases the chances of spam). Default is "checked".
  • Detect feedback duplicates: If checked, this checks comments and trackback for duplicate content on the same item by the same author. Duplicate content is probably spam. Default is "checked".
  • Feedback sensitivity to links: This setting sets a limit on how many links a comment can have before it is considered spam. If a comment has more than this number of links in it, it will get 100 percent spam karma. -1 to disable it. Default is "3".
  • Apply rel="nofollow": Number of hours to apply "nofollow" to a commenter's link(s). In theory using 'nofollow' causes search engines to not follow the link thus denying spammers any ranking within search engines. In practice it probably doesn't help because spammers target people clicking as much as search engines indexing. If set to 0 this feature is OFF, if set to -1 the time is FOREVER. Default is "-1".
  • Check referers for URL: If checked, this will search the referring page content for the requested (your) URL. This works against referer spam, but creates additional webserver traffic because your server has to fetch the URL that's given in the Referer. Default is "unchecked".
  • Check for valid email hosts: If checked, the host part of email addresses will be validated more thouroughly than a simple syntax check does: We will try to determine if it is actually possible to send mail to the host (by checking if it has MX records), and if it isn't, the email address will be rejected. Disable this option if the machine Quam Plures is running on has no access to the public DNS, e. g. if it is running inside an intranet.
