@feeleep: I was wondering why my revenues on your pool are in total 15-25% less than what they should be. Until I noticed that on >100% rounds my revenues are just slightly below what they should be while on <100% rounds they are 2-3 times lower than what they should be! The further away from 100% the more discrepancy on both ends. So I monitored the situation and saw one huge farm pool-hopping.

They hop into your pool when a new round starts. If the rounds goes over 100% they hop to another pool. It is the miner which has appr. 3.5 MSol/s and is donating (so easy to spot even for outsiders, despite the anonymous handle). This means that once the round goes over 100% the hashrate of the pool drops from 7 MSol/s to 3.5 MSol/s and the rounds get very long. Once some loyal miner who stays in the pool finds the block and the round ends, the 3.5 MSol/s miner returns just to pump the shares on the new round, getting overproportional revenues on all short rounds, while letting others do the lifting on long rounds. Sucks, because everyone else is probably losing 15-25% on average since this pool-hopper has 50% of the total hashrate of the pool.

Any chance to switch from PROP to PPLNS to end this scam?

The pool works nicely otherwise, but this mega pool-hopper sucks and steals big time from the loyal miners. Don't tell me these are the GM scammers, because there are not many people out there able to do 3.5 MSol/s.

You suck, it's not much. Renter cost hign over 30-40% normal ZEC mining cost with luck =100%, miners can dump for electric cost and go to another coins, but renters have to accept to lose by ZEC/BTC crash 10-20% rate(up to 30%/day). If you dont like, you can go to f2pool, flypool, nanopool
