Sure-but what do you do when this percentage of the class cheats - 80% or something here?

Do you fail everyone?

The percentage here is really, really disturbing. I don’t recall seeing what kind of class it was, but cheaters are usually the exception, it’s assumed.

…or maybe the whole world has been cheating a lot more than we all think.

In a wide-spread situation like this, when you have the goods on the cheaters, yes, you flunk them.
