Twitter is a subscription-based system (by this, I mean that I have to subscribe to someone's content) so if I subscribe to someone and don't like what they say then buh-bye!
Let me right click on a comment/tweet (I don't use social media so not sure of the exact terminology the kids use these days) with the options of:
- Hide this comment
- Hide all comments in this thread from
- Block all comments in future from (you can undo this in settings).
That would work for me.
