I just noticed that Stack Exchange runs a school for smoke detectors. I'm not complaining, I'm just wondering why we have one. I'm asking here because it doesn't seem to be associated with a specific site.

    Anyone can create a chat room, don't take chat room titles as anything reflecting Stack-Exchange-the-company. Jun 24, 2015 at 17:37

1 Answer 1


That room isn't run by Stack Exchange (well, it sorta is as they host it, but you get what I mean :P). It's owned by The Charcoal Team who runs a bot, SmokeDetector, that aims to detect spam on the network and posts it in chat rooms. The "Smoke Detector School" room exists for testing and running Beta features.

  • So that is who SmokeDetector is. Jun 24, 2015 at 17:37
  • So the bot there doesn't respond to commands? :( Jun 24, 2015 at 17:37

    Can it actually detect smoke? I'm just joking. ;) Jun 24, 2015 at 17:37
  • @ShadowWizard No, it doesn't.

    @PythonMaster: the spam detector bot is called Smoke Detector. Coz. it raises an alarm if it smells something spammy. Jun 24, 2015 at 17:38

    @Mart is right, when we'll have bot that can nuke spammers, it would be called Fire Extinguisher. ;) Jun 24, 2015 at 17:40
  • So I could create a chat room for those who didn't make chat rooms for themselves then. Jun 25, 2015 at 2:16

    Can I write a module for SmokeDetector that wires it to my house's fire alarm system? Please? I'm totally willing to do this.

  • @PyRulez Yes, you could -- but in most cases you don't need to, unless the people who need it don't have enough rep, or it's a room for a chatbot.

  • The back end service publishes a websocket of events so it would not be super hard to route those to your home automation. The joke gets old pretty quickly, though; you'd get around 100 alerts per day at the current spam levels (much more when Ryan is trawling old posts and reporting any we missed).
