First let me tell you how i found this out, I had a problem where for 6 hours my miner was getting paid for only 10% of his hashrate, the support team has still made it like it was on my end, during this time their own servers were going up and down, my miner would not failover to another pool because in my cgminer it was connected and hashing,thus a failover would not happen, During this problem I pointed my miner in other places for a test like they asked me to and finally pointed it back to ghash.io and mined a whole 4 hour block.
I then noticed my 50ghash/s cloud I have with them was charged a maintenance fee for 177,624 shares mined that block
I will list a few things for you to determine yourself, along with screenshots to back it up.

Now if we do a simple mathematical equation it will tell us something interesting
If you can mine 177,624 shares with 50ghash/s of mining power in a 4 hour block, how many shares can you mine with 1000Ghash/s of mining power in a 4 hour block?
Solution
177,624(20) =
3552480Wow how ironic to see that mathematically the numbers match very closely to what my miner stats output was huh?
So from this we can clearly assume Ghash.io is paying us less than 50% of what we mine, and make many excuses and avoid this situation in customer support. his first response was

Hi,
Whats your error rate on your machines? We are not a pay per share pool but a PPLNS pool so your only going to see shares credited towards blocks solved within the last 10 previous shift scores.
Try pointing your miners to nl1.ghash.io:3333 either as a primary or backup pool.
Best Regards,

Please view the same picture submitted to him NOTICE the pool I am mining in HAHAHAHA. Also, understand I already told him I had not subtracted the rejected shares from the 3+millions shares provided but even if I did it would still leave my shares provided at over 3 million.
Your thoughts??
