Worrying behavior

I came across a page a while ago on Facebook, "John King's DCEU Infographics."

It seems like the owner of the page, John King, is quite active in posting content and memes to other DC-related pages, the majority of which are just rage-bait. The more I checked the page day after day, I noticed that he gets limited interactions with people who almost always tend to agree with him, but the post rate and consistency do have me quite concerned for his mental health.

We're talking 15 to 20 posts a day, all Snyder/DC-related, and they all seem to be aimed at bashing the DCU; he even seems to think that people who don't agree with him have some sort of personal vendetta against him.

Surely this isn't normal behavior for what I believe is an adult man. Defending what you like is one thing, but when it slips into obsessive behavior that shows up as hundreds of social media posts a week, it's worrying and not at all normal. I don't think I've ever seen a page or fan group like that in my life.
