Lets see, two days ago:

"I'd join BTC Guild but pool hopping will hurt my return"
"I left BTC Guild because pool hoppers are walking off with rewards that I should have earned."
-Debate ensues, eventually someone sends me a complete breakdown of exactly what pool hopping can do for their return and shows how it HURTS LEGIT MEMBERS-

Now: 1 hour delay added
"Pool hopping is just a myth!"
"OMG WTF YOU'RE HIDING OUR STATS FOR AN HOUR I'M LEAVING"


Damned if you do, damned if you don't.

For those leaving, think about this one simple fact:  Legit users returns ARE reduced by pool hoppers.  MY RETURNS are increased because of the speed fluctuations pool hoppers bring at the start of each round.  I just reduced my income to help legit users.
