Admin for lemmynsfw here, I just wanted to chime in that I 100% agree and feel that this is a feature that needs be baked into lemmy as a software overall. People who do not want to see pornography need to be able to block it in some way at the very least. There also does need to be an overall differentiation between NSFW content and pornography as well, since it feels particularly problematic to not have a distinction between the two. I think it is likely that content warnings will come to lemmy though, but we will see. Our back-end team is currently working to figure this out to identify our specific needs as an instance, but it's an uphill battle. Hopefully connect developers add this feature at least to provide a temporary fix, and I hope other app devs follow suit.

Yes, this is incredibly necessary since stuff like lemmingrad and .ml exist. I'm sure many other people have their preferences as well.

I don't necessarily want to see a random butthole while scrolling the feed next to my gf. (I know we can blur NSFW, but after reddit, openning blurry images is an invoulantary action)

Good idea! I'll add a filter instance feature in the next release (tomorrow).

+1 - absolutely a valid use case. This would also let users filter out arbitrary instances at-will (for instance, @exploding-heads.com, which is afaict a “free speech” instance whose userbase feels a lot like the most recent incarnation of /r/thedonald).

Yeah definitely agree, there needs to be a way to filter instances from /all for the user without having to defederate with an instances.

I only want this to block mostly other language instances like feddit.de lol

I think thats something that lemmy itself needs, i however blocked LemmyNSFW in my DNS, it reduced it a lot, some stuff is still getting however.
