+
+This plugin adds antispam support to ikiwiki, using the
+[blogspam.net](http://blogspam.net/) API. Both page edits and
+[[comment|comments]] postings can be checked for spam. Currently,
+detected spam is not saved for human review, it is just rejected.
+
+You can control how content is tested via the `blogspam_options`
+setting. By default, the options are configured in a way that is
+appropriate for wiki content. This includes turning off some of the
+more problimatic tests.
+
+The `blogspam_pagespec` setting is a [[ikiwiki/PageSpec]] that can be
+used to configure which pages are checked for spam. The default is to check
+all edits. If you only want to check [[comments]] (not wiki page edits),
+set it to "postcomment(*)".
+
+By default, the blogspam.net server is used to do the spam checking. To
+change this, the `blogspam_server` option can be set to the url for a
+different server implementing the same API. Note that content is sent
+unencrypted over the internet to the server, and the server sees
+the full text of the content.

 You might look at the Wikipedia page on "Spam\_in\_blogs" for more ideas.  In particular, would it be possible to force a subset of the pages (by regex, but you'd choose the regex to match those pages which are publicly writable) to use rel="nofollow" in all links.

+Ikiwiki now has a checkcontent hook that plugins can use to see content
+that is being entered and check it for spam/whatever.
+
+There is a blogspam plugin that uses the blogspam.org service
+to check for common spam signatures. --[[Joey]]
