Myself and another developer are working on something we think will solve this:
OP: https://lemm.ee/post/2800726 TLDR: Automatic User Distribution
Whenever someone goes to the sign up page, for example, on Lemmy.world, we:
- look at the recommender list

- have a small "No, I want to sign up specifically on Lemmy.world" option
