They did -- that was just during the first week, when she was nominated. They put the show on 7-second delay that week for the first time, and they had to bleep her a bunch of times in the span of 60 seconds, while she claimed that her fellow nominee had called Julie Chen a whore (which he did, jokingly -- big misrtake when Julie's husband runs the network).
A few weeks later, there was a special power given to another houseguest to overthrow the house, and it was while she was HOH. Her nominees were replaced and someone else went home. After that she had a fit, and stopped cooperating with production. A couple of days later she was booted from the show.
