Hi,
I was about to join the
http://intensecoin.com/pool/ and when I was in the process of pointing my rigs to the pool (I have ~ 20 rigs), I got the "your IP is banned" msg.
WTF people?! Are you banning miners? Was using port 7777, but miner (xmr-stak) was changing difficulty. There is no contact email on the pool, only Slacker which I've never used and don't know how to use. And I have a static IP. Jeez! ...
Most banned cases is about submitting too many shares in a certain of time. Please try to set a static, bigger difficulty for your rigs, I believe that will solve your issue.
