Why did I get 77 times smaller reward for block #267753?

0 for these...
It looks like your hash rate is really low based on the number of your shares and the length of time on those blocks. You should probably switch to another pool that uses a pay per share method of compensation. To fight against pool hoppers slush uses a scoring method that gives more points the newer the share is. You can work out the math, but my general understanding is that any share older than ten minutes after the pool solves a block is pretty much worthless. As an example...if you had 300000 shares in the first thirty minutes of a block and then turned your miners off, if the block got solved an hour later your reward would be 0.

Some of us have experienced the issue of not being paid (or, losing pay) for shares which met the score criteria. At least for me, that was my concern. I have been slush-loyal for months, and suddenly my confirmed payout started dropping, along with unconfirmed payout, and for a couple of days with just 60gh/+ pointed at slush, I wasn't getting anything--despite new blocks being found.
Something is up. Could be something innocent/simple, as recently changes have been made to his end.
I switched most of my power to another pool and haven't had an issue. Not knocking slush, but something just seems off.
