Bans are a public relations coup; the more public they are, the more efficacious. People love to see the hammer come down.

It is happening all the time, but it's become a source of headlines now for a glutted news edifice, so we "know." That's how we found out about three especially high-profile bans, considered how a just society should corral them, and then made comic about it sort of but not really.
