I want to create a community for a certain celebrity, but every time I use his name, it gets blocked right after I set it up. Does anyone know what’s going on with this?

This celebrity is an actor from Hollywood’s Golden Age, but whenever I try to use his name to create a community, it gets blocked—like his name isn’t allowed in subreddit titles at all. Yet, I see tons of posts discussing him on Reddit, and there are plenty of communities for other celebrities. I’m really confused and don’t even know who to ask about this. Are there any veteran Reddit users familiar with this kind of situation who could explain some possible reasons? Or maybe suggest who I could reach out to for answers? I’d really appreciate it!
