Since I now have a better understanding of what happened, the most efficicient thing is for me to contact DYN and also send them this string, if nobody minds. Surprised Google hasn't caught it. My thinking is that it is a service Google offers to certain legitimate vendors so Google can charge them for it. That's more likely than all these vendors using the same provider for the receipt confirmation service.
