I have just written a very small Akismet plugin for Elgg.
When enabled and configured, this plugin will scan newly submitted comments of the ‘generic_comment’ annotation class.
While spam comments are rarer on Elgg due to the fact that most sites don’t allow anonymous comments, this could be useful for people who are getting spam comments from people who have signed up.
This plugin comes into its own when you allow anonymous comments, such as on a site I recently built for a client.
Extending this plugin to scan other content should be fairly straight forward for even a novice coder, but if I have time I’ll provide an interface to do so.
Anyway, go get it here, or check out the project page on google code!
