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’ve only had two people say they would block me. In both cases it was me asking questions about their comment and them getting angry and not having or wanting to give an answer.
I only block when people get personal for no particular reason.
