They didn't have any backups?
And that is a big mistake.
And is why all pools have an autopay feature. Having 20,000 coins in any pool is having a lot of faith and trust in that service, I don't even trust the exchanges with that amount of coins.
As it stands there are two other pools, with one of the pools actually run by one of the exchanges, that seems like a safer bet, just please don't store any coins on the exchanges and use the autopay feature.
Stopping supporting Extremecoin just because one pool has shutdown, a pool that I do not run or control, is a little "extreme", I was not the one who lost your coins, I have made this coin as fair as it can be development wise.
Thanks
