I don't know the reason why it was being removed for because the edit summary says about the description of him notably known for making a Minecraft Yandere School series. I was in a process of making one today, but I don't feel like if I can do this, nor if you will let me do that. But I want to know why it was acutally removed in 2015?
I probably removed it because the page was created without enough sufficient information. I remember we would have to constantly delete new articles because newer editors would create pages with only a small description and nothing else (i.e. no infobox, links, personal information, etc.).
I'm sure you could create the page again for this YouTuber if it meets the wiki's requirements and you have sufficient information to fill up the page.
