Unfortunately, the popular r/SecurityClearance (https://reddit.com/r/SecurityClearance) subreddit on Reddit.com is heavily censored by the moderators, and candid discussion of polygraph matters is not allowed.
As a remedy, AntiPolygraph.org has created an uncensored subreddit for discussion of security clearance matters. All are welcome to follow and participate in r/SecurityClearanceTalk:
