Ragnorak: The current method we have in place is email verification where each new account must have a unique email address. However, during times when I am running Google ads I like to switch the registration method to its simplest form in order to maximise conversions. I recently also tested an SMS verification system which would require new users to send an SMS to verify their phone number, but our trial run found that most new users found this daunting and so the next step there is to look at a system that will send the user an SMS instead though it may be costly. The other method we are going to look at closely is one which will ensure that each new user must have a unique Facebook account.
hurray do the facebook registration thing and youll see nomore of me
