ur nan came first <| sep |> If it runs via an inserthackhere . exe , even if it doesn ' t modify game files and only scans ' pixels ' Blizzard can essentially use the Warden client to ban people who ' ve been found to use it in conjunction with Overwatch . The Warden client scans your RAM and software usage to detect where your computer is dedicating usage to and to what processes . That ' s why people were in such an uproar over the Warden client ' s first announcement . They saw it as a perversion of privacy , since it could theoretically find out you ' re dedicating RAM to that Google chrome tab with hardcore buttsex . But you accept the TOS when you sign on . They use it for Overwatch too . This too , shall pass . There ' s no escaping the antihack Spyware overlord .
