It's an agency shitlist, and only the TSA knows who's on it. This list doesn't contain people who've actually assaulted agents, but people who've expressed their displeasure with intrusive gropings through words or non-violent deeds. The agency's official statements make it clear this is an arbitrary way to punish travelers who make agents unhappy, noting that it neither requires "injury" to a TSA employee nor the intent to do so. Instead, the list contains anyone who presents a "challenge" to the "safe and effective completion of screening."
