“We almost know what time of day these ads start to appear and that information can be shared.”
NECC’s Biggar said the National Cybersecurity Centre and City of London Police were looking at ways to take the scam ads down from websites. He said about 100 sites had been taken down - a small proportion of the total, but a start, he said.
Fake comparison websites will be the next target, he added.
Rocio Concha, Director of Policy and Advocacy at Which?, said:“Online advertising scams can have a devastating impact on victims, yet our research has repeatedly found that online platforms such as Google and Facebook have failed to prevent fraudsters from exploiting their systems and are falling short in protecting their users.
“Despite acknowledging the seriousness of the issue, the government has not included scams within the scope of its online safety bill. It must urgently come forward with new proposals to give platforms more legal responsibility to prevent fraudulent content from appearing on their sites in the first place.”
