There are a great many geography educators using Twitter. Sometimes a tweet triggers interactions with other accounts. How do you know that someone who expresses a different opinion or challenges what you say is actually a real person?
The Botomoter is a useful tool.
It gives accounts a score out of 5 according to how close to a typical bot they are. Luckily my main account gets quite a low score, although ironically my school departmental account gets a lower score.
