> Was there a legitimate purpose or is he just a troll?
Call attention to a real issue that should be solved by the ecosystem so that people cannot do it in the future? In my opinion it is not useful or even sane to expect people to just _not_ do annoying things if you develop systems that allow people to do things that annoy you with them. Design and build systems that assume people will be trolls, and make it so people cannot so easily troll you with them. Failing that, there's nobody to point the finger at besides the person or people who made it possible.
