Introduction

HMA is an open-source, turn-key trust-and-safety system. You can setup HMA to scan through content your users have added and flag potential violations. You can configure rules in HMA to automatically take actions when these potential violations are flagged.

HMA can pull in data from Facebook's ThreatExchange API (if you are a member) and use that to flag content.
