Right now all the moderators have jobs outside of this community, so we’re doing what we can with what time we have. Right now, that’s mostly writing and contributing to issues in the existing Lemmy. Making our own fork, and keeping it up to date with mainstream Lemmy, would be more effort than we currently have time and expertise for.
As for cross-posting, that’s a direct violation of the Reddit terms of service for use of the API. If we did that, it would get /r/blind banned from Reddit, especially in the current environment. I don’t think that would be a good outcome for anyone.
