In the LTC pool this is the second time in a row its happened.

Someone with a hellacious piece of hardware, ninja mines for a few minutes, running up around 7 million shares.  More than the entire pool has done all week.  Last time to get that 7 million, it produced 19,000,000,000, Invalid shares, thats 19 Billion in a few minutes.  This time it only submitted 26 million Invalids in that few minutes of mining.  Mining pool hub support, told me it was legit mining the first time.  7 million shares in about 15 minutes.  
That seems like petahash mining in a megahash world.


Whats happening here?  Very suspicious.  Or someone figured something out about scrypt mining, and is keeping under wraps.

Regardless 26 milliion invalids in a few minutes should exceed some threshold, but obviously did not.
