I sympathize with the large flaws in Lemmy that cause huge problems for moderators. I’d personally prefer to stay with it and continue to push the devs / community for upstream bugfixes (through PRs, open issues, or bug bounties), but I do understand if that becomes unmaintainable.

If the user experience on a new platform is similar I’d likely stay; if it does change significantly, I most likely would switch to actively use a different Lemmy instance.
