Read his timeline. That's how he describes himself. Also read his pinned message.
The nature of what he's doing could be orthogonal to government persecution, or not; I don't know.
Turkey is 1984. The opposition is in jail without any evidence. Yesterday i walked the streets in Istanbul and saw a group of 15 year olds being stopped by the police. The police went through their Facebook as I passed.... This same day a friend of my father in law was put in jail for 'undesired' content he posted on Facebook.
