I do not know the legitimacy of these keys. The site has been selling the keys for a long time over 2 years. It seems to me that Microsoft would have stopped this a long time ago if they are bogus.IMHO
The consensus around the internet is that it's iffy at best. They appear to be a site where users can resell keys for games and such. Not sure if that is how the Windows keys are sold. I didn't find them on Microsoft's partner site. Microsoft will typically ban keys as they become an issue. Sometimes keys get banned, sometimes they don't. You can search the internet for "kinguin windows keys" and see.
The site is out of Hong Kong so I'm not sure what they can do legally other than ban serial numbers as the are found to be an issue.
