Glad this didn't happen to our pool. Crazy https://themerkle.com/multiple-mining-pools-suffer-from-yiimp-hack/
That's altcoin nonsense. Couldn't affect this pool, and with kano-san on the case, not much ever will!! 
Mine On!
No for sure glad it is altcoin nonsense and not Kano's pool or any other bitcoin pool for that matter. Just crazy to think pool operaters didn't catch that when they put a pool up for users to mine on.
I know there are many pools running NOMP by operators who couldn't change or fix anything if a problem was found.
Yeah I'm also very conservative about updating ckpool pool code, coz -ck doesn't always test his changes either ... that's one of the main 'actual' causes of the split ... and why he's lost multiple blocks on solo and his new pool.
My DB changes go through the wringer checking and testing but even then it's of course still not impossible for bugs to sneak through.
I also do proper testing of the block code in ckpool, the few times I've updated ckpool, to make sure it won't throw away our hard earned blocks.
But the cause of such problems as the yiimp one can be either untested code, or purposeful hacks, but again the real issue there is pool ops who think "woo I can make easy money doing this, where's a point and click free pool that I can run on my ipad ..." or similar
But Bitcoin is indeed still the wild west and probably always will be ... as it should be
Uncontrolled ...
There's of course those who are in it to the advantage of all involved as well as themselves, but it's also full of scammers and people who think they can make a quick buck off everyone else
