I'm not a model, but I am a tragically longtime reddit user, who has periodically used the platform for promotion of creative work. Here's what I know:
I would say that absolutely no sub is worth posting multiple nudes for verification. That seems iffy, at best, and textbook weirdo reddit-brand misogyny and entitlement. Lucky for you, there's like a million erotic subs out there, so it might be a better strategy to find subs with smaller, more dedicated user populations and less creepy moderation. A user base as big as /r/milf, with so much daily posting, means you risk getting lost in the giant crowd of self-posters, and I'll say, with 2 million subscribers, based on the karma counts and replies of the average post, engagement seems rather unimpressive.
Reddit loves Onlyfans, and tends to hate camsites -- not sure why (actually, I am sure why -- wierdo reddit-brand misogyny and entitlement.) So, I'd say advertise OF or Fansly, Sticky a post with your links in your profile. Upload all material to your profile directly, and crosspost to friendly subs from there. Find friendly smaller subs with good engagement, and even start your own sub. Don't crosspost spam too much. With such a huge social media site like reddit, I've found that it's better to use a laser than a shotgun blast to try to cultivate an audience. Poke around subs that fit your vibe, don't break sub rules or themes, keep posting where you find some traction, and move on from where you get nothing.
