18. Data

19. Observations
19
– Chatbots tend to post more messages than
genuine users, with most chatbots posting
messages with similar frequency
– Chatbotted streams have a higher IMD than
genuine streams. Chatbots have a consistent
IMD showing that they are automated
– Chatbots’ message distribution is more
spread out, and on average, they post
consistently throughout the stream
