""" REST API endpoints for managing triggers.
Provides API endpoints for adding, removing and reading regular expressions that allow a
message to be passed through by a censor. A published message must match one of these
regular expressions otherwise it gets dropped by the censor. This provides a message
filter customizable by the hood admins.
