You can ask questions about that community run moderation bot right here on MSE. No one that is being hit by that bot or want to discuss issues pertaining to it should be forced to join a chatroom1 and discuss it there.
Do notice the difference between a community run moderation bot and a community run bot. We're not going to have questions here about KennyBot nor am I going to answer those.
The bots that assist the community with moderation do have a public appearance, make their presence known in some way or another. I would argue it is in our all interest that the broader community can monitor what these bots are doing, question the features it has and raise concerns where due. By ruling these questions out and directing them to a chatroom with like minded people is bound to have a biased response.
Although the code of the Smoke Detector (and other bots) isn't maintained by Stack Exchange, you can argue it does power the Stack Exchange network for moderation. Similar to how the Stack Exchange Data Explorer powers the Stack Exchange Network for data analysis. Questions about moderation bots are on topic.
To prevent an overload of questions I do propose to limit the questions to the discussion and support types related to how the bot interacts with the users on the site. Bugs and feature requests can stay on the GitHub repositories or other means provided by the bot maintainers.
