> The primary SmokeDetector repository run by the Charcoal-SE organization along with apparently every single fork has been suddenly disabled without warning or explanation.
SmokeDetector is an open-source spam detector that automatically detects and helps to remove spam posted to the Stack Exchange network, such as Stack Overflow, and has become an integral part of the efforts to keep those sites spam-free. Hundreds of thousands of volunteer hours and hundreds of real-life dollars have been invested in this project.
