look at what blocks umine credit to miners and look at what blocks get paid to its adress. they steal a lot of blocks, miners beware.
Can you share details please and not just make accusations?
I would also be appreciative if you can provide proof. If there are clear cut facts that this is occurring, I will remove them from our list of pools.
If not, please don't slander honest pool operators unless you have physical proof to back it up.
Funny that, I heard few discussions before regarding umine (not on this forum), none of them was positive.
