A) Talk to your admin about harassment and ask them to look into this when they can.
B) Start posting in communities that have a higher intolerance to this kind of behaviour (I’m thinking Beehaw communities)
C) Make a post on !anticorporate and see if you can get even more people doing it.
I’m actually thinking of adding these to my posts as well now just to see more people’s reactions. Do you know of a way to automatically add it to the end of your posts?
