reading this, makes me think about an opportunity of creating and then selling/giving freebitco.in accounts. is it allowed?
I'm pretty sure account farmers, for whatever reasons, do exist on freebitco.in site as well
looking at how massive new accounts created daily, there's a big chance this already happening
so would I be breaking any rules if I'm selling/giving out used accounts?
I don't think there's any rule about selling or giving away an account but having more than one account is not allowed.
IMO it wouldn't be attractive to buy accounts. If it is just to get full base reward you can just deposit $50 so that sets a price cap. The calculation is a ratio of free roll winnings against amount wagered with balance factored in as well. So any bought account just used for free rolls would end up going back to reduced rewards anyway. Brand new accounts are exempted from having that algorithm applied to them for the first 100 free rolls to help people get started.
