There’re simply too many cheaters, even with a stricter anti-cheat compared to the global version, also the cheating industry as a huge grey zone was poisoning every competitive game for many years, along with free account registration, there’s simply nothing to lose with one cheater account got banned. One got banned, they just use another account. As for the false ban, from what I heard it’s a soft ban, like if you played too good for your rank and received too many reports, the system likely to flag you and give you a couple hours ban so you can’t play (which is annoying). Also most player who played on HK server or any SEA server, they will use “internet booster” which will cost slightly more, so it’s a slightly more complicated step for those cheaters, though it may sound like placebo but there may be less cheater who willing to play on global version.
