Separate 24/7 Category
Make a separate section/category ("set game") for 24/7 channels and disallow such channels to be featured. This will give more chance and opportunity for general streamers to be featured and assist in their growth. If there is a section for 24/7 channels like music channels, people can easily navigate to that section.
We now have more categories to account for this, and now 24/7 channels don’t appear in top streams!
If you would like to be in a more specific category, you can also pick one of the following:
Radio (24/7 Music Channel)
Always On (for 24/7 non-music channels)
