FBI warns of fake verification schemes targeting dating app users

The FBI is warning of fake verification schemes promoted by fraudsters on online dating platforms that lead to costly recurring subscription charges. [..] It starts with fraudsters approaching victims on a dating app or site and developing a romantic rapport. This lays the ground for requesting to take the conversation outside the platform onto a supposedly safer communications tool. At this stage, the fraudster sends a link to the victim that will take them to a seemingly legitimate verification platform where the victim will have to verify they're not a sexual offender.
