Previous research has found evidence of likely automation based on numerous characteristics: posting frequency (bots tend to post much more frequently than individual users), post time (bots can post consistently across the entire day while humans need to sleep), post content (bots often post only about a single issue), post repetitiveness (bots often repeatedly post the same or similar messages), percentage of retweets (many bots only retweet other’s content), connectivity (bots are often part of groups that interact with each other through mutual following and sometimes retweeting), number of friends and followers (many bots build followers through reciprocal relationships and thus have a similar number of friends and followers, other bots will have almost no friends or followers) and post interaction (many bots will have no user interaction on their timelines).
