The fact you can block an instance where communities reside that you have issues with is incredible!
It’s like if Reddit gave you a feature to block a subreddit and all the users that subscribed to it in one single action.
Edit: OP should try creating an account on different instances? For instance on the instance hosting the community that just posted this to…?
I have several accounts and sh.itjust.works has been doing a stellar job with managing the toxicity from leaking into this instance.
The hardcore/toxic crowd do nothing except alienate and turn people against the cause and make people think being vegan means being surrounded by assholes.
It’s people like you that welcome everyone into the discussion that inspire more people to try it out; you’re bringing about the real change.
