A handy sorting feature and possible spam/quality option would be to hide worlds based on Tags.

Like if you don’t wanna see DJ venues you could hide ‘DJ Venue’ and any world using that as a tag will now be hidden from your worlds view.

Sure you could just add this as a search filter but it would be real handy for those other pages say if you don't wanna see the hundreds of FNAF worlds etc..

You could even expand this feature to be tags / relevant names so if it is a word in the name of the world also it will hide that world too. 9/10 it would be hidden anyway if using the correct tags.
