For every Youtuber out there who influences people or entertain them when playing Cubic Castles, when making videos about them and you are ready to upload them, I encourage you to use the hashtag "#CubicCastles". You can do it by simply typing the Hashtag on the description, or even make one of yours!
I've seen alot of other non-famous CC streamers who are streaming cubic castles almost 5 people in a month, and its really suprising. I saw their videos through a compilation of related videos by using the same hashtag #CubicCastles
By doing so, Youtube can compile your CC video related in one sub group panel and let other people see your videos.
