gollark: Unfathomable reaosns.
gollark: The developers of "Warship" made it leave when we added it, but we beat them.
gollark: Some people were somehow annoyed enough by their bot being here that they banned us accessing it, or some features.
gollark: There was one bot which appeared to be harvesting messages and posting them elsewhere by webhook, although that MAY have been an actual mistake.
gollark: Some.
