Meta adds scam detection tools to Facebook, WhatsApp, Messenger

Meta said in a blog post that it was adding new scam detection tools to Facebook, WhatsApp, and Messenger to warn users before they engaged with suspicious activity.

On Facebook, Meta was testing alerts that flagged suspicious friend requests when accounts showed signals such as few mutual friends or a different country location, and prompted users to review, block, or accept the request.

On WhatsApp, Meta said it would add device-linking warnings after it said scammers sometimes tricked users into entering phone numbers and device-linking codes or scanning QR codes that would link the scammer’s device to an account.

The alerts would show users where the linking request was coming from.

Meta said it was expanding advanced scam detection on Messenger to more countries this month, but did not specify which ones.

It would warn users when new chats matched scam patterns such as suspicious job offers and ask whether they wanted to share recent chat messages for an AI scam review.

If the tool detected a scam, Meta said it would encourage the user to block or report the suspicious account and provide more information about common scams.

🧠 Food for thought

Implications, context, and why it matters.

New tools arrive amid claims Meta protects billions in high-risk ad revenue

User alerts follow a report, based on internal documents, that says Meta has a financial reason to avoid broad fixes for fraud across Facebook, WhatsApp, and Messenger 1.
Scam ads that Meta labels “high risk” may bring in up to $7 billion a year 2.
An internal analysis found that universal advertiser verification, a step that could cut scam activity, would cost about $2 billion and reduce total revenue by up to 4.8%, which led Meta to push back 2.
Meta allegedly built a global “playbook” meant to slow regulators. It included making fraudulent ads harder to find in its public Ad Library (a searchable database of ads running across Meta’s platforms), to shape the “prevalence perception” of scam ads in Ad Library search results 2.

The global whack-a-mole effect of advertiser verification policies

Meta’s new tools shift responsibility to individual users, while internal documents describe a wider pattern where scammers move when one place tightens rules.
After Taiwan required advertiser verification, Meta’s tests found scam ads in those countries fell by as much as 29%, while much of the ad revenue was “redistributed/rerouted to the remaining target countries” 2.
Without broader enforcement, gains in one country can push harm into other markets, as “violating actors” move to places without verification requirements 2.
These alerts offer local protection against a fast-moving, global problem that feeds on gaps in platform policy 2.
