Unless you think people should be punished for thought crimes, that seems like exactly the right kind of "it worked" to me. You don't want to give these toxic communities a broad recruitment platform and you don't want them to destroy your forum culture. That's your right as the provider of a privately owned social network. Of course, they can go elsewhere. They can make their own website and host it in another country, if they really want to. These kind of bans are not about doing favors or not, they are about maintaining a site that you can live with as a company or private forum owner. It has been like that online on every public forum since the dialup BBS system days. If on the other they plan to commit crimes, then that's a matter for police and the public prosecutor's office, not for private companies, no matter where those groups go or meet.
