How many times can I use the referral scheme?

The referral scheme is a little thank you from us to you for getting your friends in on our subscriptions. We therefore ask that you only give your friends this code and do not post the code on discount voucher code sites or similar. We monitor the usage of these codes and reserve the right to block account access if we notice suspicious usage such as large volume of referrals or multiple referrals within the same household. However we do understand some people are just popular!
