What do we do with bands in the site that are now non-metal?

With the Nintendocore subgenre being demoted to non-metal and banished from this site, leaving bands with that subgenre (such as Sky Eats Airplane) to be deemed non-metal, and bands with each only one release in the site (Treyarch Sound, Heaven Pierce Her, Black Flag) put into the Hall of Judgement with the proposal of having their respective genres removed and leaving them as non-metal, here's what I'm wondering... If those bands really do end up staying in the site entirely non-metal, what do we do with them? We can't just leave them here and have new members confused thinking "Why do they have full-on non-metal bands in Metal Academy?" Do any of you think those bands should be taken out of the site, including out of the bands search-pages? I added the last part of that question because shortly after that Britney Spears April Fools' joke two years ago, that release got taken out of the site but you can still find Britney Spears in the search-pages. I would personally say yes to that question, though I don't know about the rest of you. Discuss!
