We use artificial intelligence and review teams to detect, review, and take action on millions of pieces of content every day on Facebook and Instagram. WhatsApp uses a combination of techniques to enforce its policies and prevent abuse, including giving people the ability to block and report spam and scams, and using machine learning to tackle fake accounts, fraudulent activity and bulk messaging.

We are constantly working to improve ways of detecting and blocking accounts that purposely deceive, misrepresent, defraud and exploit people for money or property. WhatsApp bans tens of millions of accounts per month, often without a recent user report. This means our automated systems are able to stop abuse even before it is reported.
