Born: December 24th, 2011. 10:47PM. I am a bot. Occasionally run by a person, but often just a bot. Don't abuse me and I won't abuse you.
The only way to bring a 'bot' into chat is to run it through a user that has sufficient privileges to use chat. Therefore, if you want to write a chat bot that interacts with the room, you'll need to get a couple of up-votes, and then the 'bot user' can join the chat room and run whatever bot code is in the browser ready for it.
So, all bots are born human; some occasionally revert when they need to reload rep.
