But when a massive amount of clients are greedily bouncing back and forth between servers and dog-piling on pools when a block is found; something had to be done.
The right thing to do is not some stupid API delay which will be obsolete soonish anyways - just change to a real and fair payout system!
I assume they still want to give "legit" users the chance of excessive pay during quick rounds but not for hopping users.
