I just got this email. I'm not sure if it's official, a leak, or a scam. I hope it's a scam.
Total Contacts: 2,200 pre-registered Attendees/Visitors
The list includes Contact Name, Email Address, Company Name, URL/Website, Phone No, Title/Designation.
Got one like this for BitBlockBoom before... scam.
