I wonder if it isn’t a reaction to the number of people blocking all NSFW content? Like if most of your users don't want to see porn in literally every other post and just block all NSFW as a quick workaround, then the headaches inherent in moderating adult content become much less worthwhile.
And without either blocking specific instances or blocking all NSFW, sometimes over half of “all” is porn.
I’m not anti porn but I find it hard to wrap my head around a user who is equally enjoying half their feed being hardcore videos, 1/4 memes and 1/4 news, all equally and simultaneously. Like “I’m on the bus reading a news article about the economy then I’ll check out 30 seconds of FP blowjobs and then oh, someone posted about a labor strike”? Who is that?
