A baddie's punishment is enforced by spellbinding. All contact between them and other Thinkamancers, even other baddies, is forbidden except in the course of their Duties. They are also banned from using various channels of Thinkamancy and are unable to speak. If a baddie resists the spellbinding to commit a major violation, it will automagically croak them.Erf-b3-p178
When the Thinkamancer commits the violation turning them into a baddie, their golden Thinkamancy pendant turns red and bears the image of the closed eye.Erf-b3-p165
Maggie implies that the Great Minds even have methods of detecting and dealing with heretical Thinkamancers who never visit the Magic Kingdom or accept a spellbinding.
