Well,It detects some of the background programmes as cheats!Happened to me once and they gave me 100 years ban xD,Some softwares that boost sound could be a reason also(Becarefull)
How you use the hack is the trick here. Playing professionally and using few hack features is 100% safe. I've been playing PUGB Lite and I'm past Level 11 (though not that high) with hack but not a single ban. I use a VPN and a different account other than my main account.
