I don’t know about endless. !technology only has about a dozen different users represented on the first page of posts. I don’t think Lemmy has the critical mass of users to flood the “block a few manually” response.
I do like the idea of combining reposts between communities, though. Get just one discussion going! Someone posted something interesting about books the other day. I replied, but there was no other activity.
Turned out that all the discussion was happening in the OTHER community, the one I hadn’t seen :(
Although…different communities have different moderation standards. A combined discussion like this would be a headache for the mods.
