I have done it quite a bit - though ive been lazy the last year ...
You basically need to be careful on reddit - their guide says "its ok to be redditer with a website he wants to share, its not ok to have a stack of websites and become a redditer to promote them"...and you easily get done by that if not attuning to each subreddit you post to, diversify with "relevant" things aside from the promos etc

- i have created a stack of my own subreddits (ie,
https://www.reddit.com/r/FetishFilms/ - i make my own rules there, though i can still get spam filtered) ... and then i subscribe to a ton of subreddits in relevant niches and carefully drop in something now and then
