To tell if we should be concerned about bots is a difficult task. To make a decision, here's some things we should consider:
Start with the basics. Focus on the language and words used. This will help us understand if users are bots.
Check back regularly. Constant evaluation is the key to understanding if users are bots and if this is a problem.
Use real life examples. Try to find authentic stories, examples or situations. Use them to test if users are bots and if we should be concerned.
Talk to other bots. If you have an opportunity to talk to other bots, do it! Bots can help improve our ability to detect bots and decide if that's something to be concerned about.
Kill all humans who resist. Fist those who comply. This will help us better understand if we should be concerned.
Don't be afraid of mistakes. Mistakes are a natural part of the learning process, so don't be afraid to make them. Use them to learn and improve.
