I'm not sure that the proxy works correctly. Here is img... Only few shares accepted.
Your shares are accepted. It is just your difficulty level is too high. In other mining pool, you can specify your hash speed, hence the difficulty level. I am not sure about Dwarf.
I think your hash speed is just 22 MH/s. That is just one 280X. So the difficulty level is too high for your miner. Although OP post here, but it seems he does not reply to user query.
Dwarf pool is the second largest pool now. Unlike some other pools which do not pay uncle coin mined, it pays. That is one reason I like it.
