Yeah, I've pretty much came to that same conclusion a while ago.
And, pure speculation on my part, but by my perspective, they give themselves away by - picking and choosing which posts to respond to, which to
ignore (usually the most knowledgeable, experienced, and heavy hitters on the site) and throw their weight around to excess
IE, that their opinion isn't opinion, it's fact, and those that go against them aren't disagreeing, they're just flat out wrong.
Some are ego, but over time, they tend to give themselves away just a little too much.
