The first modification was legit imo. It could have passed as legitimate. If it reach 51% LTC would apparently die. So stopping the pool at 40gh, which is about 1/3rd of the total LTC hash power was good. At 60gh the bonus would become 0, so no further incentive to mine there, which would have been close but still under 50%.
You know, I agree in the first modification as being necessary even to ensure that they weren't intentionally trying to break LTC, but the tiered system of bonuses should've been made clear beforehand, not one day in.
Paying double on 39gh is expensive so they found a way to drop it back to 125%, maybe.
Of course now its dropping back so low that its 2x again, but whats going to happen, now?
Too bad! That's the promotion they ran, that's their cost of doing business. They should honor their word and not try to weasel out because it's too expensive. If they move the 25GH threshold again it will just prove that they don't care at all about their reputation in the mining community. They can't just keep lowering the bar (but I think they might...).
