It's unfortunate that you chose to upvote what has now turned out to be a total scam. The site has now been shut down. This video is from youtube and it explains how the scam is set up. Basically, a scam organization such as btcdownloads.com sells pre-scripted bogus mining contract websites to criminals to perpetuate scams. It's basically run as Ponzi scheme - pay out a few withdrawals to generate a few fake reviews (such as the copy/paste advertorial above), then shut down in about a month or so.
Drquanta is possibly one of the scammers operating eken.io and should be investigated by steemit.com and possibly banned for perpetuating fraud.
