I mined successfully all weekend at Cat.Coinium, but when I woke up this morning CGMiner was reporting that my shares were being rejected because my "miner account was being temporarily blocked". I only have one miner account and one mining rig and my IP has not changed. My hash rate varies from 1.5 to 1.8 M/Hs so I am not a big hasher by any means. Can you help me understand why my account is being blocked?
