I’ve seen so many cases of cheaters online where even the most braindead of checks would neuter most cheats:

Are they moving faster than conceivably possible by a real player? Even the most basic (x2-x1)/t > twice the theoretical will catch people teleporting or speed hacking.

Is their KDR or any other performance metric outside 5 standard deviations from the mean?

Here’s one: is everyone they encounter reporting them for cheating along with one of the above? Do people leave their matches constantly?

Defining and detecting objectively impossible things is not impossible.

Scoring ect ... is kind of useless because it's not a proof, basically it means nothing tangible to be able to ban with 100% confidence. That's why ML is not good for detecting cheaters.

It gives a score that is hard to use.

Yeah, we do those things.

1) they’re not foolproof

2) there is a delay in aggregating the data

this has annoying effects when the game has a trial period/goes on sale/has lots of cheap CD keys floating around.

3) if you weren’t delayed then the cheaters get better at adjusting to how you catch them.

We actually do a lot of statistical analysis, but it works in tandem with endpoint anti-cheat, and would hardly work at all alone.

I know when I spent a lot of time dealing with fraud in a different market, the most effective tool was to catch and shadowban the accounts rather than banning them.

If we banned them, they just created a new account and kept doing the same things.

When we detected them and the isolated them from all other good standing accounts, only allowing them to interact with other shadowbanned users, it virtually solved the problem. Normal users went about their day and the cheaters/fraudsters wasted a lot of time never getting through to anyone.

In gaming it seems like creating a cheaters purgatory where they are stuck competing against other cheaters forever would probably end up being its own special league after a while. Like when people suggested steroids in pro-baseball should be legal.

		Yeah, we actually discussed doing something like that. That's what GTA5 did (though, they marked you with a dunce cap)... .. even though it's a good idea (and we nearly implemented it actually), there's probably a reason that GTA5 is still plagued with cheaters.
