Thanks for the link. Yes it says betting below minimum is not allowed!
I understand that betfair want profit, which gives that [punters profit]*commission>0.01 and as long that is fulfilled then betfar will get there commission profit.
But even if you bet below minimum they will earn if the above condition is fulfilled.
I understand that they will close accounts where they don't get the commission example if you green up with small profit (profit*commission<0.01), but as long you pay commission why would they close the account?
