If you need patients, why buy an account when you can go to your local hospital and get all of the patients you want for free. "The patient patient admired the patient's patience."
Facebook have some clear guidelines, and if someone don't follow that, then this is going to happen. Facebook is always things about end user not like creating multiple accounts from same IP address. Lets take an example - if they allow such kind of account then after some time what is going to happen? who is going to use facebook?.. So if you are trying to cheat some guidelines or then things twice and try to first thing how facebook work and how they track (need to have look some advance technology ) and then do such kind of things. As you know, digital agency and others are doing this but they know how to cheat this.
