The front page has a very easy to find section called "Welcoming New Fans of Ghostbusters!" which states "If you are new to Ghostbusters, please read our simple summary of the Ghostbusters Franchise. We also encourage you to read our Introduction Page, which is to help you avoid conflict within the community here.". I guess I could say we "highly" encourage you to read it, but really the issue is they not even bothering to read the front page.
So what should I do about that?! Why is it my fault that they are not willing to read our Community Portal which every normal wiki has?! I have done what I could to avoid conflict here. I think I do way more warning, than is warranted.
