I think this could be very valuable for the community and the Lemmy devs. However, I believe to be successful, there needs to be a volunteer(s) who “sync” the community to the GitHub issues. We could automate this but that would make the situation worse. Here’s how I could imagine this working:
When a new feature or bug is posted, the mod determines if this is duplicated or not. If so, they will reply to the post with a link to the previous post and lock the current one. If it is truly new, the community can vote and comment. After a week or so, if the community supports the new feature or fixing the bug, the mod will open a new GitHub issue with a summary of the community discussion and link to the discussion.
This is a lot of work for the mods, but I believe it would really add value for both the Lemmy community and the devs.
For CSAM in the US, you have to have actual knowledge to be responsible for reporting. If you view the image or it is reported, you must act. Its pretty much the same for DMCA.
