See below for the cut and paste from their conditions. It is from section 1, part 9
Another question tho, is how exactly does MF place small bets? It may or may not be breaking the below condition.
Minimum and maximum bet stakes
Depending on the product or type of market you are betting on and depending on the currency that you are betting in, there are minimum bet sizes that apply. These minimum bet sizes are subject to change and may differ depending on whether you are on our site or using the Telephone Betting Service. You are not permitted to place bets or try to place bets that are below the minimum bet size threshold and doing so may result in your account being permanently closed.
