Genuinely want to know what you’re referring to (unless this is a joke) because I’d be very happy to leave Lemmy. I’ve been waiting for Sublinks to be primetime ready
No, I think it just blocks all lemmy.ml communities. Not posts/comments made by ml users on communities from other instances.
In my experience, it did greatly cut down on the tankie posts and comments I was reading because ml users’ political takes are mostly contained within their own instance. I only come across tankie takes once every few days now. And I’m on lemmy a lot.
And dubvee.org if you’re from the glorious wild and wonderful state of West Virginia, America’s very second best Virginia (thus making it probably in the top 5 of all states in terms of my weird nationalistic appreciation of them)
