This is a viable solution, but all of them using a single account in the same site seems like a better solution which I suggested in my earlier post.

I know you have already been answered but I want to make an official response. The whole point of giving you a free play is to get you to come to our website where we can market our services to you. If you use any form of automation or even get someone else to roll for you then you are cheating us out of that free roll and giving nothing in return. That's why using any script is forbidden in rule one of our ToS.
