Why dont more users just block communities and instances they dont like? Thats what I do, and I almost never see the sort of extremist content people have mentioned.
That's why the subscribed feed exists though, right? Sorting by everything is a good way to find new communities to subscribe to occasionally, but I wouldn't use it as the main way to browse. Of course there's going to be things on there people take issue with, its literally everything.
Because it doesn't work. Blocking hexbear throws an error on kbin. So does blocking users from hexbear. Other domain blocks don't work at all. All the feddit's for example. Hope the next update fixes that.
