Filter for bots?

A Reddit user is seeking ways to filter out bots, noting that many subreddits discuss the prevalence of bots and their negative impact on the platform. The user is unsure about the exact number of bot-originated posts or comments and is looking for effective methods to prevent AI-bots from posting. They are also interested in human-only verification processes that subreddits could implement to stop bots or agents from spamming.
