On mention by DJLunacy i thought this would be a nice one to code up quickly. All code written after 1am so there may be some bugs, but tested fine for me.

This mod allows you to ignore all posts by a user simply by clicking a link in their profile. It does not break the cache in any way (JS+cookies). To remove them from your ignore list, edit your profile and you can click to remove them in an area near the bottom of the edit profile page.
