After enjoying another batch of ten spam posts in "Recent actions" I decided to write a small userscript which would analyze the contents of Recent actions section and deletes from it (and from the main page body) posts written by spammers.

Criteria for deletion (all 3 must be fulfilled):

• Post author is unrated.
• Post author doesn't belong to a white-list (MikeMirzayanov + several other well-known users).
• Recent actions contains at least two posts by this author. Typically a spammer publishes 5 posts within a couple of minutes and then disappears forever. So two-post limitation allows to keep singular posts by honest unrated people, as long as they are writing reasonably often :-)

Well, here is the actual script: http://userscripts.org/scripts/show/486645. If Install button doesn't work (looks like userscripts.org has some problem now), you can copy source code from http://userscripts.org/scripts/review/486645 into a file called cf-hide-spam.user.js and run it separately.

Let me know whether you have any problems with it, and what you think of it in general :-)
