Penalty level 4 for breathing air??!

I was farming chainmail 2s in a party area then i got a message on chat colored red saying that there will be a maintenance so party area finished and i got kicked from the game to the main menu cause there is a maintenance i left the game and waited for many hours then i got back to the game maintenance finished entered specia 1 when i found a message on the middle of the screen saying "You no longer have access to chat and other services" i clicked close tried to send messages but it was restricted i searched about it and found out that its a penalty level 4 and its a permanent penalty i immediately contacted the customer support asking for a reason of that penalty and why penalty level 4 why not level 1 and all they said was "Once a penalty is applied it cannot be removed" like what???!!
