Aside: Is HN so fragile that it requires end-users to police anomalous activity? Given the age and influence of the platform I'd assume dang and co. who moderate and maintain the board are old hands at staying on top of manipulation of the platform.

Could any mods comment on this? _Should_ we be keeping an eye out and calling out odd activity? It'd be nice to avoid posts like __blockcipher__'s; while well intentioned I could see such commentary having a chilling effect on discourse.
