basyaru please run latest daemon ASAP. If not, we will ask miners to abandon your pool.
Nanopool should be considered hostile at this point. (1. stealing hashrates, 2. DDoSing Suprnova and then 3. the time-attacks) I think it makes sense for every miner to abandon them.
1) We made the same code change, the latest release has, 3 hours ago already. Developer has written in email what did he do in the code.
2) Our servers properly synchronised and our block time is correct.
3) We don't make any DDOS attacks, but we DO have a DDOS protection.
4) "stealing hashrates" is an absurd thing, as you can not have the same effective hashrate on the pool side, as your miner shows. You lose some time to achieve work and to send it, have some % of invalid shares, miners pause mining on job changing (good ones do it quick, but still has a break).
The better miner works, the better connection is the closer your pool stats to the miner reports.
5) The REAL attack was shifting all the pool blocks timestamps to 30 seconds in the future, making it impossible for our pool to mine any blocks in next 30 second after Suprnova finds a block until we've applied the fix.
