Did you not ask your IPTV supplier where he gets his Sky IT Streams and how he opens it on CCcam ??
you obviously are convinced its h@cked and working , i personally see Zero Evidence to suggest its anything other than IPTV or someone Re-streaming IPTV directly from an IPTV source it really wont be that complex that will be certain , but most likely its not beyond possibility that Sky IT simply getting Re streamed from an IPTV plugin on someones E2 Box to your supplier then to you .
the CCcam information screen i imagine can very easily be manipulated as we all know how badly compromised CCcam is as an Emulator
and a simple fake splash screen would not be all that hard to Fake whatsoever .
IF Sky IT was genuinely working on CCcam you would most likely be the 2nd last person on earth to be notified about it that is just how it is i'm afraid , and every forum plus social media would no doubt be full of adverts about it which is far from the case .
