We would like to empathize that the users participating in our advertising campaign and being paid for it, have nothing to do with this incident.
In any case, given that there is no request from the law-enforcing authorities or real proof from the exchanger, we continue to insist they return the full amount to the user. Today we have switched the exchanger off until this situation is solved, their investigation is dragging on and they do not provide and new facts.
Glad to hear your response on this matter. Personally I think this situation should be an eye opener and would like to see the 100% safe claim from your landing page removed. I'm going to revise my feedback, but still feel that's an unreasonable goalpost to have and is unattainable.
For me the campaign participants weren't wrapped up in this at the moment, as the potential scam is off your platform you were just the gateway and they make up a small percentage of where you direct people.
