Certainly! The following userscript will remove Real Stuff posts from the front page, and from the sidebar. It will not remove them from the BBS. It's also available here.
Be warned that the posts will flash on screen before being removed, and that there is some risk that this will remove unrelated posts with similar titles; I will try to update the script on userscripts.org if it becomes a problem. Please let me know if you have any comments, though, as you can see, it is an exceedingly simple script.

This userscript is being provided as a service to those who have requested it, and the many here who seem that they would appreciate it. It is not intended as any sort of judgement on the worth or taste of Eichhorn's work, of which I will merely comment that venue impacts appropriateness.
