Blackmail scam
Abuser: Unknown - Random Email with Message-ID from @mx.google.com
Extortion email requesting $1650 paid to a bitcoin address. Two copies of email (with separate bitcoin addresses) were sent to same email address within a 12-hour period. HTML Body of emails used a huge amount of <font> tags with a 3D, Transparent, 0-size format containing random content, apparently to give it a "scary" look by having tiny content/shadowing next to the regular characters.
