FanBridge, stop spamming the crap out of me

Every day I get about 3 or 4 pieces of spam from FanBridge, the email delivery service for bands.

Normally email delivery services like Constant Contact, iContact etc make sure that you opt in to the list before they deliver email from their customers to you. They provide the valuable service of mail deliverability by ensuring that users want to receive these emails.

FanBridge claims on on it's website that users must opt in to receive messages, but this is a bold faced lie. So FanBridge, how about it? Will you stop spamming the crap out of everybody?
