Not really a bid bot, but a bot nontheless. "[TribeSteemUp] pools SP and has an automated voting list for [anarchistic] content creators". It was created by @kennyskitchen.
I am not affiliated with TribeSteemUp in any way, but I keep running into posts, so I googled and found this.
This video explains TribeSteemUp well. Very interesting. Thanks, @redsandro!
