I have plans to open source linkbot once I clean up the code. It was thrown together in a couple of hours yesterday, so it’s not well formatted. However, someone just commented on another post that they had just finished their bot and posted it to GitHub. I haven’t looked into it at all, but you can find the link to that comment here.

Just to be clear… this is not the source to linkbot. The creator of this rss bot is @kensand@lemmy.kensand.net
