I mined on this pool with 1.5 KHS for more than a day. Earned about 0.00085 BTC (as it was reported in "Confirmed Exchanged Balance" on "Staticstics" page). Then stopped. After a day my balance become 0.00005 (yeah, 4 zeros instead of 3!). I made a payout which is still pending for a day.
So I believe it's a FRAUD. 

Just avoid it.
