You can't nullify it. As the time goes on, you'll learn to avoid id most of the time. And when you can't avoid it, you can file a protest, if you think somebody's behavior was unacceptable. It won't affect your rating or incident average, but they'll get warned or suspended, and (hopefully) learn not to do it again.
