- Elon has stated that bots are a problem for Twitter
- Bots were most likely largely operated via the API. Or at a minimum, used the API as a data source for targeting and crafting of tweets.
- If not the API, then using web based automation tools
Therefore, if you want to drastically reduce the number of bots you should:
1. Remove the API free tier and/or drastically reduce the feature set of the paid tier
2. Raise the cost of tweet creation e.g. Twitter Blue and paid verification
