This one is response to JP thread about spectator mode.
JP thread doesn't go into specifics like the NA thread did so we may hear more from NA rep on the NA thread. I just read below and was like, hold on a sec, NA side had ways to work around this... so I translated the NA post and posted in there below Foxclon's post.

When we release the coloseum event, we are looking into 3rd party, spectator mode where they can view the fight. But as for the raids and other battle contents, we don't have any plans currently.

その理由としては、動画やスクリーンショットを勝手に撮影されてしまいトラブルに発展する可能性や、そもそも他のプレイヤーに自分のプレイを見られたくないという方もいらっしゃるであろうということを配慮しているためです。
The reason being that if someone takes movies or screenshots it could possibly lead to some trouble, also other players may not want to be watched.

Talk about it in there please!
