We’ve been made aware that it is no longer possible to identify posts as NSFW in a NSFW community as of Lemmy 0.19.11 (https://github.com/LemmyNet/lemmy-ui/pull/2887), and as a result some posts appear to be not marked as NSFW.
While some apps (Voyager is the only one I have personally verified) do correctly flag the posts in NSFW communities as NSFW by default.
We’ve verified on 0.19.11 Lemmy will blur the image and not tag the post as NSFW, but we haven’t verified behavior from older instances viewing our communities / posts.
Due to the current time as of writing this, I’m not able to investigate further until the morning but I hope this provides some basic information on the situation for now.
Update, Apr 27, 2025
We’ve updated Lemmy UI to a hotfix version of 0.19.11 that re-enables the NSFW field on the Create Post form for NSFW communities. This should once again allow users to correctly mark posts explicitly with the NSFW tag.
While a permanent fix is in development by the Lemmy team, please ensure you check this NSFW toggle if you’re posting to a NSFW community.
Thank you for your understanding and patience.
