I worry that most Lemmy instances are too young/inactive for this kind of bot yet. I don’t think we’re past the tipping point where the people commenting will automatically outweigh the bots, and I don’t think those bots are fun unless they’re dramatically outweighed by normal human interaction.

That's an interesting way of putting it that I didn't immediately consider.

I don't necessarily like them, but I'm not really all that against them, either. If we don't have the activity to balance out bot input, however, it might be reasonable to limit them one way or another. It seems to me like a worst-case scenario, but if a community or thread has what feels like a noticeable amount of bots, that would be a turn-off for me.

If the community decides to limit bot traffic either partially or entirely, it might be good to revisit that decision later on if there's an upward trend in users and activity.
