RSS subscription bot?

Hi,

I generally manually post articles of sites that I think are interesting to the fediverse by hand. For most RSS feeds this is the only practical way to do it as it's never "guaranteed" that an article from a site is going to be about a specific topic. For example, anime news network posts aren't always about anime, etc etc.

However, there's a general interest I have in trying to adapt both RSS feeds (and, maybe later, news letters) to automated posts on specific categories on lemmy for certain communities where it's easy to do this. News posts for specific games (think steam RSS update feeds) and the like.

So the questions I have are:

1. Are there any open source projects that are designed to integrate with piefed with a bot user handle by subscribing to RSS feeds?
2. Does anyone actually employ this on their end and what does it look like?
3. Could RSS subscriptions be a per-community feature (depending on the instance)?

Thanks!
