Tried the pool for a couple of hours with a cgminer at 260Mh of scrypt.
Average hashrate accepted by the pool was about 180Mh, no matter how I played around coins and difficulties.
Unfortunately, it was a rented asic, so I don't have access to its logs.
I'm not going to make any accusations, but the fact is that my experiment got 30% of hashrate lost for some reason...
