Content Moderation

Content moderation is the practice by which social platforms review user-generated content and remove, restrict, or label posts, accounts, and media that violate their policies. It's how platforms claim to prevent illegal content, harassment, and spam — and it's the mechanism through which critics say politically inconvenient speech gets silenced.

What it means

Moderation is a spectrum. At one end: removing child sexual abuse material and credible threats of violence. At the other: labeling a politician's post as "misleading" based on an opaque fact-checking process, or removing an account for using a slur in the context of condemning it. The challenge is that the same infrastructure and teams doing the first type of moderation are also doing the second — and the second is where the political fights happen.

Most platforms moderate using a combination of automated systems (AI classifiers that flag content) and human reviewers who make final calls. Both are fallible and subject to the biases of those who design and operate them.

How it works on Gab

Gab moderates for illegal content under U.S. law — CSAM, credible threats, doxxing with intent to harm. It does not moderate based on political viewpoint, religious expression, or content that offends advertisers. This is a deliberate product decision. Gab's founders argue that viewpoint-neutral moderation — where the rules apply equally regardless of ideology — is both more honest and more consistent with free speech principles.
