Guess what happened.
The kids these days don't know what normal pings looked like back in the day.
Nobody banned me. But yes players accused me of cheating of course. Back then I also didn't know what "netcode" is. Now in hindsight I know that the game gave an unfair advantage to players with high ping. Probably in order to make the game playable with internet connections common at the time. Blame Valve ;)
No cheating involved. Best ping I ever had at those times was 120-150ms IIRC. On that particular server it was more past 300.
Boy those were the times.
Not sure how you think you could get that from actually cheating.
We all know cheating is a problem in online games, so it wasn't an unreasonable belief. It's certainly possible to play chess at Magnus Carlsen's level, but if I play against someone random online and they play at that level, then of course my default assumption is going to be that they're cheating, not that they're Magnus Carlsen.
