Either way, I had no idea Twitter muting worked like this, where you could actually mute TYPES of tweets, and not just content IN the tweets. I don't think they go over this in their docs: https://help.twitter.com/en/using-twitter/advanced-twitter-m... - I wonder if they will block this or break this if it picks up steam since it would lower their engagement numbers some (half the reason they stuff all this extra junk in your timeline, to begin with).
I can't imagine this is something that's intended or expected, but I could be wrong. I'm guessing OP is going to end up regretting posting this awesome little "hack" once they change it so it no longer works. haha
