They have rules against using their services for that kind of stuff. Once they're made aware of the rules being broken (which they were), they should enforce the rules by stopping service. The same as if you report CSAM on a website to the hosting service and they take down the site.

I've been PC gaming since 8-bit computers. I eventually bought an Xbox One as my first console and a Switch some years ago. I just couldn't get into either of them after the initial novelty wore off. PC gaming is so much more convenient for me. I'm already at my PC, I just need to start a game. And I can multi-task with other apps in the background or on my second monitor. Going to the living room to play on a console on the TV, or switching inputs if I keep it attached to my PC monitor, both are too much hassle. I only ever use the XBox for Just Dance (nothing beats Kinect for it) and I've played many more hours of Switch games on an emulator on my PC than on the actual Switch.

In all your examples, k is a prefix to the unit. You can have 1 km, or 1 kdB. But there's no such thing as a kilopercent and that's not how it was used in the title. It was the common informal shortening of 1000 to 1k. So it wasn't 1(k%), it was (1k)%. Which is an odd combination. It's not confusing, everyone understood what was meant, but it's still stupid and unnecessary.
There you go
