If you don’t mind it being a different sublemmy, you can just request it at !requests@lemmit.online.
If you stay within the reddit api limits of pay for it, yes.
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: !whowouldwin@lemmy.world has received 3 posts ever as opposed to /r/whowouldwin/ which has over 400,000 subscribers and receives dozens of unique posts every day.
It’s possible
I want to know how such a bot can be deployed.
i believe they typically run as a service on a computer, monitoring the subreddit via the reddit api, the when it finds new stuff, it posts it onto lemmy.
I am yet to see an implementation of this between Lemmy and Reddit. That does not help.
