Strange thing.
After a reddit post, I tried out BTClevels and even won some money, about 4 BTC.
After phase5 claimed btclevels is a scam, I decided to withdraw my funds and everything went well. I've withdrawn 4BTC back and still have a small amount on account.
Here is my account statistics:

As for me, I will definitly use BTClevels once more.

There was a similar article in the BusinessWeek about half-year ago:

Why this tread is dead for about a year?
This app is pretty good, I can do all my bitcoin staff with it: monitor workers, sell bitcoins.

What miner and pool are you using?
Try to contact pool's support, 50btc team helped me to configure my miner.
