What could help regarding clickbait titles is to add a short description in the body about the video content (“This video is about [topic]”). One short sentence shoud suffice.

Good idea, but perhaps as request instead of as a rule.

When creating a post containing a video there is an option to auto-suggest the title, as it is often the same from the video source. Most posters use this, as it matches the video title from the source.

I’m not sure about this since a large amount of videos are from YouTube which blocks the request to fetch the video title in Lemmy.

I think video titles shouldn’t be changed, no matter how much clickbaity the titel is, because the video most likely is named the same on the original source (Youtube mostly).

Are you okay with the current status quo of asking people to do so but not removing posts that don’t?
