I recently started messing around with ActivityPub, Mastodon and Lemmy and created LemmyLink, an open-source bot that seamlessly bridges Reddit and Lemmy. Triggered by the phrase “LemmyLink!” in a Reddit post title, body, or comment, the bot automatically creates a corresponding post on your chosen Lemmy instance. This allows Bidirectional post and comments between Reddit and Lemmy by triggering a Reddit bot.

Feel free to play around with it on r/LemmyLink. Simply include "LemmyLink!" anywhere in your post title, body or comment on the LemmyLink sub. This is setup on my own Lemmy instance lemmylink.com currently not federated and marked as a bot to avoid spamming the Fediverse.

There are some pros and cons to bridging communities but I think if done with transparency and user opt-in it could serve as an interesting way to bring more users in to the Fediverse. But, I'm curious what others think.

How LemmyLink Works

Only works for Subreddits and Lemmy communities specified in the code Reddit users include "LemmyLink!" in their Reddit post or comment LemmyLink posts the Reddit comment or post to Lemmy LemmyLink responds to the Reddit post or comment with link back to the Lemmy post The code is rough so go easy on me but it is available on GitHub: https://github.com/ateames/LemmyLink

Feel free to fork it, suggest improvements, or simply try it out.

Don't we already have this over at https://lemmit.online/?

Not to discourage you, but expect this sort of bot to be banned on reddit side very quickly. I had way more innocuous reddit bots banned without reason or recourse.

How about have the bot detect community crossposts and try to funnel the conversations into one post.

I fear, this "to be created" "sync feature" is going to create a lot of noise.

How does it know in which community to post?

You have to define the specific community in the code. You can specify the Lemmy community LEMMY_COMMUNITY_ID and the instance URL LEMMY_BASE_URL in a config file. The code then routes to the community in the config.
