I have 2 bots..

Mary Botzzapp is a publish only. Writes a note once an hour to the relays it's connected to.

Polly Botzzapp is more involved. It connects to relays with subscription and listens for direct messages, as well as any zaps on posts that it is explicitly monitoring. Direct messages are how it lets you create and manage polls and it replies in mind. When polls are started it publishes them, and same for when a poll is expired or ended.
