Interesting request.

Strangely enough, it seems there isn’t much on that area yet.

Maybe people on Lemmy don’t want to get motivated, or on the opposite are motivated enough.

Is there any other interest you would have? You can usually use https://lemmyverse.net/communities to find some

I’ve made !getdisciplined@lemm.ee but I haven’t gotten round to making the bot that reposts r/getdisciplined posts to it yet. You are all still welcome to subscribe for when the bot does eventually drop

These have been a few but I can’t find them in my blocklist, so maybe they have died.

Ok it works now: !getdisciplined@sh.itjust.works

lemmit.online has(had?) a bot taking content from any subreddit you want to, and then put it in a community with the same name.
