Interesting I didn’t realize there was research on this stuff. Yeah maybe I should go to beehaw too. Blahaj is another one that disables downvotes. It’s true theres no full account migration but theres ways to export your settings and subscription etc to a new community (see this or this). Apparently theres also ways to link two accounts for a persistent identity, by putting the other accounts username in your bio or something, but I don’t know a lot about that.
