DOA is extremely niche though, you can't expect huge viewers for the game when the community is rather small. Some players only got huge views at some cases because he/she had already streamed a long time to the point of already having consistent followers. Sometimes you'd have to find the right day and time to stream as well.
To get people to watch your stream, you'd have to get consistent people who are willing to stay to watch in the first place, and that sometimes is rare for DOA. While I understand your frustration, making a topic about it realistically speaking isn't going to help.
