Awesome article. I think Medium might foster more of the good old-fashioned billygoat trolls, because they seem to put a high premium on engagement, and a proven way to spark fake engagement is to pick fights. Therefore, block/report/ignore is by far the strongest tactic. I'm new here but it's the tactic I use on Twitter, and I intend to use it for Medium as well. I mostly write for ebook retailers, and there the tactic I use is a lot of pen names. I don't have the time for people trying to mess with my income to score some sick kind of point.
