The website is very unclear. What sort of data? Who would be cleaning the data? What type of data cleaning? What types of payment? How is access to the data controlled? How is the data cleaned? Are extra data views to help data cleaning provided by the site? How are bandwidth concerns addressed? What does user karma signify? etc etc.
I have no idea what your website does.... After landing on it. Extremely confusing.
Please provide an example.
So is this meant to be a security enhancement website? If so, why aren't you using HTTPS by default (or even outright blocking HTTP)?
We can run your user data by our AutoML tool http://ForecastApe.com and add a predictive power estimate to each dataset. In fact it is like adding a dollar tag to their data. So they could thus justify cleaning it.
But did we really want to share our unclean data to 3rd party ?
