The site offers numerous rankings of graduate school programs covering 100's of programs and explains in one short paragraph what data were used to do all that. No source for the data is given. I teach computer science, so I looked most closely at the computer science program rankings. I found a school in the website's 2016 and 2017 rankings that merged with a nearby state university in 2015 and no longer exists as a separate entity. Other than those rankings, the site has "articles" which are no more than infographics on random topics taken from other providers. The site is completely anonymous; it has no names, phone numbers, or addresses.
