Does something like this exist? As far as I can tell, setting something similar up would require:
- A dedicated Lemmy instance for Mastodon tag-based crossposting (probably, since most existing instances probably don’t want to clutter their instance with thousands of script-generated communities)
- Some kind of form on a site where users who want to follow a Mastodon tag that is not already set up as a Lemmy community could submit the tag they want added, which would automatically set up:
- A Lemmy community for that tag on the aforementioned instance, and
- A Mastodon hashtag bot that automatically crossposts all posts with that tag to the linked community
@xigoi @Anbalsilfer Not everything is federated yet, but of course we are part of the same network (= #Fediverse ).
For example, I can reply here from Mastodon (from #Friendica #Pleroma etc. it also works) and also make posts in Lemmy communities (by tagging the community account).
