Cmon, you know we aren't supposed to post that information on the forums. Regardless of their denial of botting, it's not cool to ask or post such information.
I think you could safely assume that MOST streamers are gearing or grinding in their non-stream hours with bots. Any who aren't are wasting their time.
You can definitely look up the "Brother Chris" reference for some lulz.
I think his reference is to watching the bot's performance in the video. It is clear that the bot is doing some wonky things that a well tuned and setup DB doesn't have issues with.
