I know the distraction thing may be a reality, but that's where the school should back her by punishing students who try to undermine her authority or bring up her porn past in the classroom. Just give them detention, Saturday school, and the usual line of punishment. There's no reason she should be fired unless it was because she wasn't good at her job. It's only a distraction if you make it one, and if the kids want to pass the class they will stop thinking about her ass. If I had a kid in her class I'd tell them that it's no excuse for their grades, so they better pay attention and do well like I expect.
