Skyyr is not a hack, he is just very good. As for multiple accounts, HTC has never had in issue with that unless it was used to spy. Its easy to see Skyyr is not spying as he streams his flights strait through.
Bottom line, send Hitech an email, or call him with your issues.
So does logging on as Skyyr, Skyyr II or Skyyr III or Rusyn for about a minute (or even fighting for a bit) on one team then relogging as either skyyr, skyyr II, Skyyr III or Rusyn and attacking that team he was just on count? Because he has done that several times and others have even commented on that in game ("wasn't he just on our team"). He doesn't stream the "pre login" Then there is the issue with him and TheJudge or other "theDamned"on separate teams at the same furball never killing each other but racking up kills on "less experienced" guys. That actually happend to me, his teammate was on my side and I was chased by skyyer form outside of radar range and made course corrects as I did, I was 100' feet off the deck half a dar ring and pulling away. We already knows he uses teamspeak or discord to talk to his buds on other teams from his own youtube videos. Spin it how you want, that's wrong!
As to hitech, sent email, zero action or response.
