I'm interested in something similar. I want a bot that reposts the top 3 daily posts from my favorite subreddits to their Lemmy equivalent. I don't want to flood the Lemmy communities but I think we can all admit most of them could use more activity.
Example: [email protected] has received 3 posts ever as opposed to /r/whowouldwin/ which has over 400,000 subscribers and receives dozens of unique posts every day.
By the way why are people able to do that? I see that person's username is mojo by hovering over it but at a glance it's just emojis.
