Cointellect has a pool : stratum+tcp://66.55.92.73:8000. You don't have to use the miner they offer on their site, but you can point your own miner on it. They have a live-feed published of one of their datacenters a few days ago: http://dc.cointellect.com/

I can't tell you if it's all real or fake, I don't understand their business model (it's way better than any other cloudhashing company), but I know quite a lot of people that are actually making profit there.

I was wondering if you really try to talk with people of these companies on phone and try to get the information you need or that you only decide if it's a ponzi or not based on what you see on their sites or rumors you heard.

Btw Genesis Mining might be legit, but is absolutely not profitable.
