[Question] How can I hack safely? topic

I recently got an Overwatch ban on my new account when I never even played a Competitive match. Can you get Overwatch banned for playing community servers and casuals (arms race)? Or are the Overwatch bans linked to accounts? I have an Overwatch ban on another account, and I was wondering if I got banned because of that.

So, what games does Overwatch watch? Everything or just competitive?

And, how can I hack in competitive without getting banned? There are a lot of hackers in Global Elite, but I have no idea how they are not Overwatch banned yet. What set-up would I use to stay hidden?

Also, I was on a community server by myself with 2 bots and I was just spamming headshot aimbot because I got bored. Could it be that the admin was watching and was an Overwatcher?

Thanks for the help, guys.
