You are banned because you left the game (F4) then the server. Then you rejoined the server, joined back to your team and then to spectator. I warned you ingame about 4 times. Maybe admins need the ability to torture a user with low voltage electricity shocks, only to say "hey this is a serious warning". Hmmm seriously no, i would have to much fun with that feature, i can't lie
I can't follow your strange story because you have to push all your buttons with your nose to join, left, join, left, specator, ... and ignor all warnings.
The server logs all players activity (from the last 100 players / steamid), if you left a game in a round or go to readyroom you get a point. If so this point is logged in another file for 30 days. When you reach the limit of 10 points you will get banned by the server. This was no manual permanent ban.
Anyways this system is online and still in development, i was online to test it, so i saw you "pressing all your wrong buttons".
Ban removed.
