One of the internet’s largest communities for Amazon employees, the subreddit r/AmazonFC, which has 43,500 members worldwide, has banned all mentions of unions, Motherboard has learned. 

A moderator of the Reddit community told Motherboard that moderators of the online forum decided to censor union-related posts, both pro and anti-union, “due to an influx of spam and outright malicious posts.” The posts don’t “fit the nature of the sub[reddit] and we will not be a platform for either,” the moderator said.
