Online dating which is free until you want to send or receive messages (like most).
A dummy profile with nothing in it returned a dozen or so responses from 'people' who wanted to know me, of course, to see these you had to sign up. Having signed up, you pay for a month minimum, but find subscriptions are 'auto-renewed' and to cancel you are required to telephone a number which, according to reviews on Qype, people had a hard time doing. Online cancellation doesn't exist once you've signed up and email cancellation is rejected - initially at least!
I advise anyone NOT to sign up and if they have and don't intend to renew, CANCEL renewal instructions by email or writing to the bank (which is REQUIRED to follow your instructions).
