Running some numbers on FTC block 87906, 15 minutes @ 900 MH/s should have been about 12.35 Million shares for the block. The actual number was 12.385 million, well within the margin of error. The payout on the block looks fine during that period, which leads me to believe it was just a display problem in how the numbers were shown on the web page.
Hopefully, it shows me as having done no work over the last three hours, but both my miners showed plenty of shares submitted. I expect to mine at a slight loss though, the reason I still want to it anyway is because the weather is getting colder so the heat kicked out by the computers isn't a waste, my gas heating hasn't come on once yet as a result so it's saving me money there as well as earning a bit.
Edit: To be fair though the price of many alt-coins is down at the moment in relation to BTC so that could be the real reason for the low earnings.
Anyway, it's getting late. I'll check back tomorrow to see how things are going with the pool.
EDIT: It seems that you might be right about it just being the pool's website telling lies, I just looked again and the hashing rate graph for the last 24 hours has changed completely, showing just occasional spikes.
