You could. I removed it from my copy. It was causing too many problems because the word REAL got repeated once per reply. So after a while it would be Q REAL REAL REAL REAL REAL REAL REAL REAL REAL REAL REAL REAL REAL REAL … TRIPCODE … post.
Not sure in what order the javascript for the site and the user javascript executes. Apparently each reply was triggering your javascript and appending another REAL into the DOM.
I love the yellow highlighting and really appreciate your javascript.
