the bots I used in the past would only respond to what you wrote in to respond to certain words. Like if you said "show" for instance I would have it tell the times the shows are being played and so on.
Bots cannot go rogue unless someone learns of a backdoor and can operate them. command lines such as /response = #show time=/format dark matter 6pm central/stop by and join us in a discussion, can all be changed if you know the secret backdoor which is a certain command setup by people who write these incase their own bot strolls into their forum spamming ads.
