Comment Warning

Description

Comment Warning is a plugin for blogs that currently use a DoFollow plugin, CommentLuv, or KeywordLuv (or have used such a plugin in the past). It detects visitors arriving from URLs that indicate that they are likely to be potential comment spammers and ‘warns’ them of the blog’s comment policy, via a JavaScript modal ‘popup’ (not a real popup).

Both the list of triggers and the message are customisable, allowing you to control who is shown the message and what they are shown.

It is also possible to redirect potential spammers to a URL of your choice, either immediately (bypassing the warning) or after a certain number of potential spam visits from the same IP address. Note: the number of visits calculated only includes visits where a trigger is tripped (not if the same IP address visits your site via a different method) and includes page refreshes.

Other Features:

  • Records visitors who have been warned, allowing you too see instances of warnings (in the Log).
  • Allows you to navigate directly from the Log to the Edit Comments page for warned commentators IP address, so you can see any comments they’ve left.
  • Allows you to see if a comment author has been warned, when browsing comments in the Admin panel.
  • Allows you to see if a comment author has been warned when you get new comment and moderation required emails.

Compatibility:
I suspect that this plugin will NOT be compatible with WP Super Cache at this point. I will be doing some testing in the near future and, if necessary, changing the plugin so it does work with WP Super Cache.

Support:
This plugin is officially not supported (due to my time constraints), but if you leave a comment on the Comment Warning Support page or contact me, I should be able to help.

FAQ

Are there likely to false postives?

The default set of triggers have been chosen to be as ‘wide’ as possible, catching as many potential comment spammers as possible.

One side effect of this is that there may be some false positives. In trialling the plugin, I have encountered almost no false positives, but the possibility exists. It is therefore not recommended to redirect users immediately. The default warning message acknowledges that false positives are possible and asks the user’s indulgence in reading the comment policy.

To limit false positives, the comment warning (or redirection) will not trigger for terms that are in both the refering URL and in your page’s URL. If you have a post with dofollow in the URL and a visitor arrives from another site with dofollow in the URL, there is a decent chance that they are not a spammer.
