No they wouldn’t.

• I don’t typically browse lemmy in a way where someone could see over my shoulder. (using thumbnail modes where I have to very deliberately go fullscreen for any images)
• This isn’t unusual. I’ve used this very image, and even more arousing art, as my desktop and phone wallpapers. My city has public art installations featuring both male and female nudity.

I WANT to be able to tag content accordingly. Because I myself would like better control over my feed. Luckily Lemmy divides things into communities and instances, through subbing and blocking accordingly we can all very precisely curate our feeds.

NSFW tagging has an literal implied use case, for which it is effectively useless. It isn’t how it is actually used, and is as such a wildly inaccurate way to exclude anything. Least of which is the fact that sensibilities vary, as to me this less than what public art shows, and to you its porn.
