We have stopped receiving spectator applications long ago. But if you want to earn the spectator mode to shoot some cool videos, here is what you must do:
1. Shoot good videos of the game without spectator mode.
2. Upload them on your you-tube channel.
3. Tag them with @tankionlineen so we can notice your videos.
We have a separate staff actively looking for potential candidates to offer spectator mode to them. They judge the videos, their quality, originality, editing features, etc. So if your videos catches the attention of our judging team, they will contact you.
Also here is a guide for Modeless Spectator Mode, check it out: http://en.tankiforum.com/index.php?showtopic=265820
