yeah, i know, i was quite sure some people would question my method...,
just try get yourself the reward bonus, its active for 24h and you HAVE to roll it 12h just for it to pay for itself...

if i was to be the bad guy in some sort, i would be the last person to give ideas...

@mods/admins
now to the ideas, since limiting the daily rolls is not an option.
i was thinking, ok, those botnets use captcha solver service, right?
simply maintain the captcha on the page after the free roll and keep the roll button on the page as refresh button (dummy), and of course the timer somewhere else..., get the picture? looping them out ;P
