Turn the ads
you block
into evidence.
Scam ads steal from people. Fraud ads steal from businesses. Reports from your ad blocker help Fray investigate both.
We've been running Fray in our own ad blocker since early 2025.
Check the account.
Gather the evidence.
When a platform removes an account, its ads stop reaching other people too.
Help protect people
without an ad blocker.
A scam ad can be blocked on one screen and still reach someone else. The account behind it can keep buying ads, finding new victims and costing people and businesses money.
Your reports help Fray investigate that account and send evidence to the platform. If the platform removes it, its ads stop reaching other people too.
Catch the ads
automated checks miss.
Scammers can hide from automated checks. Your ad blocker can report what appears in a person's browser, including ads our own checks miss.
We handle the investigation, filings and disputes. You get a feed of confirmed scams to help protect your users.
Work with FrayYour privacy comes first.
No user data is ever collected.
Your informed and explicit consent is required before enrollment. Your ad blocker then shares only information about the ad creative with Fray, never user data.
Our approach to privacyFree to take part.
Funded by Marcode.
Fray is run and funded by Marcode, a brand-protection company in London. Our paid fraud detection work funds the investigations, so ad blockers and brands can take part for free.
