The kink of going out of your way to comment to a user who is not even interacting with you that they "need therapy" because of their kink (which obviously the drive-by harasser does not like, even though it is a consensual, legal, adult human kink that is not hurting anyone). I saw a very popular user on here do that once, and I Googled to see if people who have the kink which the the drive-by hater claimed warranted therapy actually warrants therapy, and golly gee, surprise, it does not warrant therapy at all, as most kinks in general do not. But then, I don't really expect any SW rando to actually have a professional psychotherapy background, I only expect them to be trolls, even the well-liked popular users are often trolls too.
Similarly, there is a clique of bored childish users here who will tag each other on the posts that reference the same kink, seemingly just to get their friends to join in to mock the kink, rather than to just keep on scrolling to posts they actually like and/or block the content they don't like. This clique seems to be of a certain bratty age range, so maybe that childish bored mob behavior is to be expected in general, with regards to anything.
Most kinks in general, so long as they are only between consenting adult humans and no one is being killed, are just another area of subjective preference; just because you don't like this or that kink does not mean there is anything wrong with anyone who does. Thus it's just petty to make a hobby of harassing people with kinks that you don't like.
If you think they're a catfish, or a child is in danger, or an animal is being abused, or they're a sex worker or otherwise trying to sell something or steer people to a commercial endeavor (spam), that's another matter entirely. If the only thing they ever post if fetish stuff, then sure, in that case they probably belong on FetLife, not SW. But usually the brat clique is just randomly picking on random isolated posts, until their ADHD takes their attention to something else and/or they seamlessly slip back into their more community-beloved personae and mothball their random drive-by hate mode for a little while.
Most forms of attempting to "gatekeep" SW are just pointless endeavors, when you could just scroll on, mute or block instead. Even the contingent who routinely spout "SW is not a dating site" are factually wrong, which they could easily discover just by visiting their own account settings — "dating" is explicitly in there, by the conscious choice of Andrew, the site founder. Do you really think he doesn't know it's there? Oh c'mon! Gatekeeping is a helluva drug.

Moreover, AI porn is not the only reason AI in particular is awful. All of the ills of AI are well-documented in the last couple of years of mainstream journalism, for anyone who isn't living under a rock, and in meantime it is only snowballing unabated. You have to be delusional to love AI and feel the need to post AI anything on a frequent basis, or generate media of anything (image, audio, video) yourself, just for the sheer environmenral footprint involved alone. I unfriend people over this AI crap.
