According to an article on Techworld, Microsoft is actively seeking a person who leaked a preview version of Windows Home Server onto a blog site.
The version was leaked to TheHotfix.net blog by a user named "Richard" soon after it was released to a small group of testers.
In an email to testers, Kevin Beares, the Windows Home Server community lead at Microsoft, told Most Valuable Professionals (MVPs) whose name contain "Richard" that they will not have access to the beta until he finds out who is behind the leak.
"I will work with the Connect Admin team to determine which one of you is the real culprit of this leak," Beares warned the testers.
Beares said that if the person who posted the release "comes clean," he may "have some discretion as to what actions [he can] take."
According to Ethan Allen, the owner Hotfix.net, Microsoft has also employed "spies" on in the forums on his site to try to find out who is leaking software previews, and has contacted him directly in an attempt to find the leaker(s).
