I'm not sure what kind of details you're looking for?
They probably means you should name the opensource project that "bullied (people) for greeting others".
In particular: did you witness the instigating incident, the bullying, or both? Did the bullying actually weaponize a CoC, or is it your impression that the presence of a CoC empowered the bully? Is "bullying" your characterization or someone else's? And so on.
