I don't like that I might be responding to the same anonymous users after they have spewed disgusting and hateful crap at me, especially since it can be difficult to even get the offending content removed. Is it possible to block the poster of particular content without being able to know who they are?
No there is not but I sure wish there was. I don't allow anonymous posters on my questions now but sometimes they can be annoying on other comments. I remember a guy was just begin so mean and tried to go back and forth with me and even when I stopped he continued and spammed. I could not black him but I reported each comment and they were all taken down.
