I think this might be useful for some kind of automatic aggregation of content from other communities or some specific cases. For example, I liked, when I was on reddit, the subreddit RedditRead on which each post was generated from other subreddit comments, one post by book found in the comment on a specific post in another subreddit. I thought about setting up the same here when I have a bit more time… Now, the posts would be all generated but users could still comments, so it’s not purely artificial stuff…

Maybe one alternative would be to authorize such bot content generated communities but clearly flags them as such in the community sidebar or so. So people who are ok with generated content can subscribe and those who don’t like can block.

In a general way, I have bad feeling about strong rules (except for stuff obviously wrong or destructive but here I don’t think it’s the case), and prefer case by case monitoring. In some cases it can be good for the community and in other very bad, and I find that saying just “it’s forbidden” is too easy and frustrating decision.
