I’m wondering if I’m just missing how to do this. I don’t want to see posts from porn communities when I’m browsing sync in public. I’m OK with blurred NSFW posts from communities which are not marked NSFW. I would really prefer not to have to filter out every single one manually.
Log in to your account on a browser and you should be able to block NSFW at the instance level. I believe the NSFW filter in sync doesn’t really work now that the block is on the instance.
