I was offered a Scuba.Digital attendee list. What is it all about?

We too have already been offered these lists. You can be assured that this is a SPAM email. Please ignore them and do not respond to them.

A typical wording reads:

“Dear Exhibitor,

Are you interested in acquiring the “Scuba Digital” Post Attendees list? Let me know your thoughts, so that I can send more info on this like cost, counts, and samples.
