If you want another angle on the story, consider non-bot bots. (aka "sock puppets")

You have an argument with someone on twitter and the next second 4 or 5 newly formed eggs with 1 follower apiece pile in to defend the other POV, sometimes without regard to civility.

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.
