Moderation
The systems and people that enforce a platform's rules — filtering, reviewing reports, and taking action against violations.
Moderation refers to everything a platform does to enforce its community rules: automated filters that catch spam or banned words, human review of reported content, and enforcement actions like warnings, suspensions, or bans.
On a well-run platform, moderation is layered: automated systems catch obvious violations in real time, while a human review process handles reports that need judgment. Users are usually given tools — like blocking and reporting — that feed directly into this system.
Moderation quality is one of the biggest differentiators between chat platforms, since it directly determines how safe the experience actually is, not just how safe it claims to be.
