I saw this a few years ago on Reddit and wish I had saved the thread because it was pretty interesting.

I was reading a thread between two users that seemed totally normal until a user posted a screenshot of their comments. It showed a second conversation between them that was happening in secret. If memory serves the person who posted the screenshot said it was an extension (possibly RES) where you view certain tags and allows you to see the extra comments based on the tags.

After seeing that I couldn't help but wonder how many secret conversations were happening out in the open on Reddit.
