My apologies if this is posted twice, my first attempt has disappeared.
I have blurring enabled in my settings but as the attached image shows, the nsfw picture in the link preview is not blurred. I’m not sure if this is new functionality, I just haven’t seen it before.
Yeah I figured it was probably more trouble than it was worth. It hadn’t occurred to me either, I was very surprised to see it. You could maybe blur anything that has nsfw in the community name or in the url, but meh, I more wanted to throw this out there than anything. :)
