No, I assume that the bots would only repost the most highly voted content. If a bot were to post everything, including low-quality content, the moderators could simply ban it.

As for having the bots in another instance, people are going to go to the instance with the most content, and that would be the bot instance. Do we really want to drive the users away?

As for different communities, people who don’t want to see bots can disable them in the user settings, so the communities wouldn’t change for them. I don’t see the point in having bot communities.

I don’t agree that a bot would steal content. Content creators need exposure and they post for free on Reddit, so why wouldn’t they want the same here?
