i also have an issue with the difficulty setting..they say they use vardiff but they do not have that option for me to check it. i need to manually put in a value for minimum difficulty. how the fuck can i choose vardiff? also this is the only one pool that is not nicehash compatible because of this shit. if anyone knows what setting should i use for minimum diff please advise.
Nope, not the only pool.
Mine is also, I block rentals and stop them whenever I find them - rentals are a financial risk to mining, due to the fact they make a financial gain from withholding blocks if they are not detected.
i think i did mine with miners and also with rented hashing power on kano..but that was in the good ol' days. i would surely want to see more blocks from kano

and from the pool operator point of view more hashing power more blocks more fees colected..and your 5X block system of reward was good in keeping the mining hoppers away. slush has also a good system against this.
now, back to my issue....
