banned for 12 hours
If you feel like this is an error you can contact support. If not wait out your suspension. Account suspensions are not necessarily instant and could be due to a language violation you are guilty of hours or days ago. It depends on how fast support tracks down and researches the report.

ArenaNet doesn’t necessarily ban you right away. It could have been something you said a week ago. Or possibly just after you last logged off but the effect of the ban doesn’t start until your next attempted log in.
In any case, nothing we on the forums can do for you, it can only be discussed by submitting a ticket – though to be honest, your ban will probably be over before they get back to you, as they can get very busy.
