Somebody starts a thread in good faith. There are a number of forumites interested that participate in a civilized discussion, but sooner or later the thread is discovered by one or more obnoxious trolls. The "report" button seems to make no difference, as trolling seems to be covered by "free speech" in some moderators' view. It's aggravating, disruptive, and makes reasonable people leave the discussion, and maybe the site.
