Interesting example I stumbled across: Match.com typically take your subscription fee every 6 months, they won't remind you before they take the money. They also won't let you unsubscribe immediately after they take the money, they claim that payment is still in progress, even though the money has already been taken. It's not until a few days later that you can unsubscribe. Essentially it seems that they've realised that the most likely time for someone to unsubscribe is immediately after they pay, because with 6 months of membership it's easy to forget that you've even got a subscription unless you're a very active user. I consider this to be a dark pattern because it plays on people's forgetfulness. My Rules: - Give people enough warning before taking payment that they can reasonably be able to decline the transaction. The only real reason someone should miss this warning is if they're taking a long vacation. - Don't do evil stuff after taking payment to prevent them from unsubscribing from the next payment - Have a nice buyers remorse window, allowing a user to reverse the transaction that's already occurred.
