I have used this guys pool from royalcoin days and I only got 50% of what I should make. I switched to another pool and immediate makes double of what I got. I thought it maybe just a config issue and since I didn't spend much time on it, I wasn't 100% sure. Well, this guys' WDC pool is the same. This time I was on it for 16 hours. CGminer reported double what he reports (valid+invalid shares). Now I tried to cashout, it's not working. Was able to get a payout finally. Definitely a SCAM questionable. This guy should be labeled as a SCAMMER questionable.

edit: I was able to get a payout. But my personal and true experience with both his RYC and WDC is they pay only half of I should've made. This is not due to fork or slow ping:

Chain forking does NOT change the # of shares. It only moves your valid to invalid shares. As I said, the total of valid+invalid was only half of what CGminer reported locally. I also configured CGminer to drop stale shares, with this option stale shares are not counted. Until erundook explains why this is, I think this pool is questionable. I changed the title to questionable until he can explain this difference.
