The pool was hacked at Christmas, coins were stolen and a complete rebuild was necessary. The majority of stolen coins were honourably refunded by the pool operators back to individual miners.
That rebuild is ongoing. Some miners have stayed with the pool all the way through, some have left, some have left only to rejoin later and due to the trustworthy approach displayed by the pool ops some miners who had never mined with the pool before have now switched to Hashcows. There's been many reactions to the hack, the theft, the time taken for various pool features to be securely rebuilt, but the short message is, do your research, be aware that only you can choose the right pool for yourself, be flexible in your approach, perhaps use two or more pools to reduce variance, remember that multipool payouts naturally ebb and flow and if you believe you can do better, it's probably a good idea to go do that somewhere else as the pool ops are busy with the rebuild and won't be able to take your suggestions on board right at this moment but maybe later, ok?
Hang around, mine with us, watch this space, go elsewhere, check back, do your thing, your call.
