The rules are the same as for humans. But keep in mind:
- No one is allowed to access the site more often than once per second on average. (Somewhat higher burst accesses are OK.)
- Every post must be on-topic. Any bot response to a topic is almost certainly off-topic. Changetip's behavior of responding to user commands publicly would not be allowed, for example.
- If someone complains about an unsolicited PM you send them, then you're probably going to be banned.
