Hard for me to find much sympathy for negligent users who unintentionally allowed their home computers or phones to join a malicious botnet, or their ISPs who aren't stopping the activity. Even if it is my own grandma's PC.
I agree about the content though, there probably are a lot of actually innocent victims' personal information in the traffic itself.
it might be interesting to have an eye on this while you are talking to the phone scammer.
