Blocking keeps my feed nice. See people being assholes? Block them. See a post discussing something I don’t want to hear about? Block them. See a community I don’t want to hear about? Block them. The greatest thing about social media is the ability to never have to interact with someone again at no detriment to them. Blocking is good.
Default lemmy feed is almost entirely left-wing content. By blocking half of these people it’s still all left-wing content. As a Lemmy user I wouldn’t really proud myself for having a diversified feed even if I didn’t block anyone.
