@mcc I spent a lot of time star-fishing on Twitter and Facebook, trying to get people to change their behavior.
I'm not sure it's useful. It may be the case that you're not here to change their behavior so blocking without explanation is fine and if they want your wisdom they can do the bare minimum work of, like, reading your profile or something.
(I mean, unless you are here to change their behavior; not telling you what to do. "I'm a shitposter, not a cop." 😉 )
