To be honest, I haven't seen a ton.
Unfortunately, my experience is usually after the fraud has occurred. It has already happened, so that prevention piece hasn't really worked in those cases.
However, I would definitely agree with your comments that there appears to be a lack of support in terms of reporting, dealing with that fraud: where to go, how to report. I think there is a lack of support from the telecommunication companies in terms of providing guidance on the primary scams that are impacting their clients currently. I definitely think there could be a more collaborative approach in terms of their running those campaigns for their client base.
