All Voyeur Sites do that to their Members sometimes. Depending on the Situation. When someone Purchases a Premium Subscription they may pay $39.95 or $44.95 for a Months Subscription but the full $39.95 or $44.95 does not fully go to the Voyeur Site Directly. The Payment Processor Collects a Fee from each Transaction made and the Remainder is Paid to the Voyeur Site. What those Fees are I have no clue as each Provider has different Standards & Rules on their Fee Policies.
If a Member has Cancelled too many Subscriptions and Demanded Refunds each time where the Voyeur Site incurs Losses on the Fees Paid to the Payment Processor then the Voyeur Site is Within their Rights to Refuse any Further Service to such Individuals that cause them a Loss.
