Polbot
A person who will repeatedly share political posts on their social media accounts. They will sometimes do this so much that they end up representing a simple-minded, singular-task bot, who's goal would be to repost as much as possible. Usually found on Instagram stories, Facebook, or the retweet feed of Twitter.
Emma, a white, teenage girl that goes to our school, posted 32 Instagram stories in 24 hours about disbanding the police and Black Lives Matter yesterday. She is such a polbot.
