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
Yep. It’s a problem. Some saw it coming. Some prefer to hype over the power of the protocol without acknowledging the importance of what’s built on top of the protocol while leaving is users in the lurch.
I suspect the solution lies in more advanced clients and giving up on wanting each platform to be able to do everything.
