For a neat paper that actually has some nice hard evidence about what government production of social posts can look like, check out Gary King and co. at Harvard's exploration of Zhanggong, China:

It could be a coincidence.
Or it could be that the person you were debating let their ID out in another way.
Edit: Just to be clear, I was talking about the Freudian "Id" in all caps, used these days as a short-hand for a sort of unfiltered emotional inner child, and not "I.D." which is short for identification.
