A "list consultant" has approached at least one company that does business with newspapers with an offer to sell them an Excel spreadsheet listing conference attendees with contact information. It is a fake list.
The only way to receive a legitiate Excel spreadsheet of actual attendees is to become a sponsor or exhibitor at the Mega-Conference. All sponsors and exhibitors will receive an Excel spreadsheet – from the Mega-Conference organizers – listing conference attendees several weeks in advance of the conference.
If you are contacted by anyone else, under no circumstances should you give them any credit card information, and please immediately notify Lindsey Estes at email@example.com or (410) 838-3018.
