Not long ago, a spam attack of epic proportions led to calls for a moderator which, at least for some time, were heeded. Spammers were banned and a captcha added. However, other than this, no moderation has been effected to my knowledge.
This moderation irritated some of the core members of
/prog/ to the extent that they formed progrider, which is fiercely moderated in that non-programming discussion is moved to the lounge board. Shitposters are banned at the largely reasonable whim of the progrider admin.
