This is a marketing exercise, nothing more.

The thing that gives it all away is that they claim that the IP addresses are from Azure, and then proceeded to redact the IP addresses, as if they belong to individual users. It's laughable.

The IP addresses are the most interesting part of this experiment, as it would have provided researchers a way to understand the distribution of IP addresses used for the spam operation within the ASN.
