Is this guy a real person? He never posts anything or replies to anyone, but he seems to favorite and repost everything I post or repost.

Just looking at his timeline, it's all reposts and most of it is either stuff I've posted or boosted. Though given that "lurker" is in his handle, maybe he just prefers to lurk and view other people's post.

If this guy is real, hopefully he doesn't get offended by me talking about him. I just don't like the feeling of being stalked by some bot.
