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.
