Try to make it more clear that this is not a flawless rating (as that is impossible).
Ways to implement:
Make sure the bot says something along the lines of “MBFC rates X news as Y” and not “X news is Y”.
Make a caveat (collapsable) at the bottom, that says something along the lines of “MBFC is not flawless. It has an american-centric bias, is not particularly clear on methodology, to the point where wikipedia deems it unreliable; however, we think it is better to have this bot in place as a rough estimate, to discourage posting from bad sources”
If possible, add other sources, Like: “MBFC rates the Daily Beast as mostly reliable, Ad Fontes Media rates it as unreliable, and Wikipedia says it is of mixed reliability”
Remove the left right ratings. We already have a reliability and quality rating, which is much more useful. The left-right rating is frankly poorly done and all over the place, and honestly doesn’t serve much purpose.
