It's just a theory of mine, but I think it's because it's easier to convey a scene within just a few panels than with photography, which require more effort to convey what it exactly is about.
Anyone can just create a porn instance, so why not as long as it's moderated (and hopefully not full of illegal content)?
There’s a new group over at /m/bdsmcommunity, a kbin magazine for people who want a safe and porn-free space to talk about kink!
The community doesn't seem to load for me on lemmynsfw.com, which is weird since other communities from kbin are able to load just fine.
