Sorry, I did not reply to this in more detail earlier.
Yes, studios do retain all copyright. But most studios also know that single images shared here and there (rather than entire imagesets or large galleries) are good for their own business/promotion. For example: I mod !ftvgirls@lemmynsfw.com as well as r/FTVGirls, and they are generally fine with folks sharing their content as long as proper attribution is made (such as model name and leaving studio logos intact and not cropped out).
Some studios are/have gotten very aggressive recently - see this https://www.reddit.com/r/BrandiLove/comments/xhhnir/rbrandilove_is_back_please_read_this_to_know_what/, whereas over my 5+ years modding on Reddit, I know many studios have never filed DMCA claims for single image posts…
For content from OC (amateur and/or sellers), for me it’s mostly a courtesy aspect - most OC posters on Reddit for instance don’t know anything about LemmyNSFW and don’t have a presence here.
If you haven’t yet, please check out !modcoord@lemmynsfw.com and add yourself there. And join the conversations with site admins via the Matrix chat rooms.
