Bots of this type have appeared recently, and people are asking if it's okay to use them. I'm not sure about this either, so I think it would make sense to ask users.
These bots follow some subreddits on Reddit and automatically post it to Lemmy when a post is created there.
I've seen an example site for it: lemmit.online. This instance is dedicated solely to mirroring Reddit posts to the Lemmy instance.
Maybe instead of mirroring to a community on Lemmy NSFW, we can subscribe to lemmit.online via Lemmy NSFW. This way we could have kept Lemmy NSFW free of bots. Currently, even if accepted, I believe it should be done under admin control to prevent duplicates.
Here is the poll: https://strawpoll.com/polls/PbZqRw82byN
I'm open to suggestions.
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'm assuming you're not thinking about the moderation side.
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.
