I think it is totally unnecessary limitation that you are hidding rigs that hash below 1MH/s. It's annoying even for me but i'm only checking for rigs because you have to turn on "<1mhs" bottom over and over again (variable is not set in url).  Every rig shoud be visible and renters sould select filter that they wish! If you will not change this i'm moving rig out of betarigs to leaserig.net And they even pay more....
