In my experience, may of these companies (Riot, et. al) are not particularly consistent over time or in the application of even current rules. And it's also hard to divine what "would be considered cheating" by these companies as one support person may say something is cheating, and another might consider it cheating and ban your account.

It seems very fraught and risky to use for gamers who desire that their accounts don't get banned.

That's good if it helps get cheaters banned.
