This is classic case of deceptive "negative option billing" (http://en.wikipedia.org/wiki/Negative_option_billing). At BillGuard (http://billguard.com) we see 10's of thousands of people fall into these kind of shady business models and its our mission to end such deception and financial abuse. It's pretty amazing that this is still legal and that VCs are throwing money at it. Even the famed post transaction scam by Web Loyalty Group was backed by a very prominent VC. Money sells.
