Is your pool still up or not? carbonshark.com has no GUI/front-end or is down (and a couple of the other pools listed here do not work either - if your pool is intentionally taken down, you should really try to update your comments suggesting people point their hashing power there. Miners should be advised to make certain the pool is alive and healthy before wasting electricity and/or money!).
ViaBTC Bitcoin Cash pool has been stable, but payments/earnings have been fluctuating to the tune of plus or minus 250% on a day-to-day basis. That is on PPLNS payment mode, perhaps I will switch to PPS+ and see what happens..
