Managed to progress through the tutorial missions!

I bravely joined a stream that was helping with the tutorial, and after watching 5 streamers, I managed to clear most of it, except for the 120-minute watch time. However, I forgot that the streamer had said it was okay to spam messages, so I spammed a single hiragana character. I think they mentioned it wasn't allowed on Playo announcements. I wonder if it'll count as completed.
