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.
I wish Lemmy natively supported the tagging feature you mention but I’m otherwise pretty happy with the web interface. I generally keep app downloads to a minimum. Which app do you use, I hear people mention the tagging feature more and more lately.
