I have been using the service for about 2 months now and I have noticed a huge drop off in the payouts. I take payouts in BTC but would like to know what's causing it and if I should stick with it.
Scrypt mining is pretty much dead, so I wouldn't reinvest anymore into it. Don't invest any into their SHA256 mining which equally sucks. Go with AMHASH, I've been getting damn good payments from them and they are the most transparent company so far.
