There are two sides to this project. The first one is that I have setup a Lemmy instance (alien.top) which is mirroring some of the reddit content from subreddits that I wanted to follow with the comments. The difference from most mirroring bots is that, instead of one single bot account mirroring all content, the system creates one account for each reddit user that is being mirrored.

The other part of this idea which I believe is more interesting: reddit users can take over their own mirrored bot account on this Lemmy instance. The instance itself does not use the regular registration process, but instead authenticates via Reddit OAuth. If you login through through the "Portal", we can then grab your subscribed subreddits and (when it can) find the corresponding Lemmy communities and subscribe you to those automatically. At the moment there are not that Lemmy communities that are being mirrored because I've been the sole user, but hopefully if more people sign-up, it will help to create the network effects and more instance admins will be interested in hosting these "fediversed" communities.

All of the code is open source (https://github.com/mushroomlabs/fediverser) and I'm more than willing to help people getting their own instances if they don't want to use alien.top itself.

Questions and any type of feedback is always welcome!
