Illustrations of BLOC action strings (\(p_{1} = 1\) minute) for a human, a cyborg, and a bot Twitter account illustrating some behavioral differences across these individuals. If strings are tokenized using pauses, the human account has the shortest words (average length 1.35 vs. 3.88 for the cyborg and 4.0 for the bot) and is dominated by isolated retweets and replies. The cyborg account — which we created to post threads of news updates — exhibits both human (isolated posts) and bot behavior (thread bursts). The bot account mainly generates retweet bursts
