Looks like someone listened to your advice perhaps.
Nicehash has been removed from the list of pools at Zencloud now for those mining SHA256
I had this message pop up on my zen cloud dashboard.
Removing Nicehash SHA256
ZenClouders,
Due to an issue that may affect the stability and reliability of our service, we have adjusted our available pools for SHA256 in order to protect the investments of our customers.
Anyone currently mining on Nicehash SHA256 will soon be automatically switched over to BTC Guild.
Thanks for your understanding and continued support.

New edit:
I want to say that the bounty question was caused by my rush . Eric of zen mentioned to not post details here on bitcointalk. I had a miscommunication with him and posted details my bad. Eric then said the would not pay the bounty.
Frankly talking on pm's at 1:00 am
was my mistake I was tired and misunderstood Eric. Posting so fast was a mistake on my part. I got a lot of people going in lots of directions over this. I know I pissed off Eric and he said no bounty. To defend him it was late at night I dropped a bombshell on him and spam filters caused a lot of people a lot of grief.
on the good side some real fixes are offered to this problem in the discussion on hashtalk.org so for now no nicehash but this idea below has promise
https://hashtalk.org/topic/5145/nicehash-sha256/737?page=39
since westhash/nicehash had rapid price flux someone proposed a one month average I thought a diff jump length may be enough to fix it. cost of driving price up 10 or 11 days in a row would be more then enough and easier to detect.

I am in contact with Gaw ceo and he asked me to say a few things.
I am trying to be fair. So here goes.
I stumbled on this problem. I tried to contact Eric and zen on zen hashtalk it was late last night and there was some miscommunication between the two of us. He asked me to not announce what I had found. I said okay He wanted emails explaining the flaw. I sent multiple emails to him. He kept saying I was not sending emails. I made a statement that I did not believe him. I posted what I found here. In retrospect I suppose I could have waited longer to release the details. I did not I released them. My 1:00 am thinking may or may not have been the best thinking.
Well the nicehash sha 256 mining option was ended on zen-gaw. I have to say I have caused quite a few angry people. I wish that Eric's spam filters were not working as hard as they were in retrospect I would have waited to release this to see how they handled the issue. I think I was mistaken and most likely Eric really did not have those emails.

In defense of Eric and Josh of Zen and Gaw they closed the mining op for that pool they did the correct thing.
https://hashtalk.org/topic/5145/nicehash-sha256/3 They ended the nicehash -sha256 option

I locked the first try at writing this thread I decided I want to be able to moderate the thread.
I had 4 s-3's they mined at westhash and at nicehash. I sometimes would get huge spikes in price on Nicehash and westhash. Often getting 2x normal payouts. I did not understand why but noted it as something I would look into. I did not understand why anyone would pay for sha256 hash at 2x the going rates.
I sold off my s-3's . I purchased 2 asicminer tubes.
I was mining at mmpool.org with a pair of asic miner tubes. Why a small pool because asicminer tubes have pool choice limits if you use the stock controller (thanks fried cat).
So two days ago I thought I saw a flaw in mmpool.org's method of running the pool. The pool is small around 50th. I decided to test my idea out. It involved buying large hash from westhash (a nicehash partner) I purchased blocks of 30 th or 50 th even 100 th on and off from westhash and pointed them at mmpool.org sometimes the mmpool.org got up to 130th of which 80th was all mine.
After 30 hours of testing I spent about .75btc doing the tests I decided my idea that mmpool.org was flawed was wrong. I did raise my btc due if it ever hits a block and would kind of break even if the block is hit soon. The result I was looking for did not happen. Sometimes an experiment can give a different result then you were looking for.
I drove the price up from about .0245btc to .0307 btc on both westhash and its partner nicehash. After I stopped the btc spending price dropped down to about .025btc
I realized this has other results. I own an s-3 hosted on zen-cloud and point it at nicehash.
here are scheduled payoffs for all zen gear pointed at nicehash
Payoff are .0307 per th. now for 1 zen cloud s-3 this means you get .0145 instead of .0095 a gain of about .0050btc so no one would spend .7500 btc to gain .0050 btc. But If I had pointed the extra hash at cex.io/ghash my .75btc would have paid back around .5btc so I would be spending around .2500 btc to earn .0050 now we all know that makes no sense at all spending 50x the btc units to get 1 btc units for the 1 s-3 is silly a waste of money.
But zen cloud is full of gh in the sky.
the top ten are more then 100th total
Those people would be paid 100 x .0307 = 3.07 btc instead of standard 1.9 btc - 2.1 btc so that is around 1 btc extra on just the top ten sha256 miners. This could have cost zen-gaw big bucks. I like or should I say liked this company or maybe I should say I have had a hot and cold relationship with the company. They have been very nice to me and at time really fucking stupid.
I am basically an honest guy so I decide to post a thread to them. I fear they have been robbed more then once by manipulation on nicehash by someone buying on westhash. I have seen huge over paid sha256 hash and could not understand why people would overpay for sha 256 hash. This reason is really good reason.
So I do the right thing. I posted this thread.
I have more to say but I am going for a swim. Be back in a few hours.
