[help needed] Followliker with multiple handlers

Hello,

I read a lot about followliker.

Now, I am about to buy Followliker, "Instagram + Twitter Edition",
IT WILL BE A GROUP BUY.

I want to know,
If I can share it with my friends as well, who are working with me,
who are using their own internet connection. AS, IT WILL BE A GROUP BUY.

Will there be any problem, if we use it , one by one OR at sametime?
On different connections & places? Can we use it this way?


also,

what works best with followliker, proxy or vps?
any recommendations?

Thank you!
