I actually did use sub.rehab when first coming here, although it may not be obvious by my account history because this is a third account (migrated from kbin.social to kbin.cafe, now I'm on kbin.run). Searching again today gives only a Squabble link when I look for r/rabbits or r/bunnies alternatives.

This is the first I'm hearing about Lemmy Explorer, possibly because I'm a Kbin (well, now Mbin, a Kbin fork, because my instance owner swapped to that. Currently to find an small instance with an active that still runs Kbin, so not the big flagship kbin.social) user. Thank you for sharing.
