Cheating In Galaxy of Heroes [MEGA]

You should be thanking the person who posted the video, reaching out to him and determining how the cheat was accomplished and what you can do to the game to prevent it the future. APK hacks can be guarded against. There is detection that can be done run time to see if an authentic APK is attempting to post fight data. The fact that's it has not been done is scary.
People are angry because there has been 0 transparency about this and community efforts to inform have been met with threats. Get your act together and address this issue. This should be of highest priority.
