I didn't want to give up this tip but I'm not into adult content so I'll share it here.
This method can take time but is guaranteed to work, I tested with only 5 posts and got 2000 visitors in 2 days.
The first step is to create a NSFW Reddit account that you will use for this method.
The second step is to find a list of Subreddits with either inactive mods or no mods at all, I searched for two days and found at least 30 Subreddits with no mods at all and another 30 with inactive mods, meaning mods have no activity for more than 3 months.
Subreddits with no mods means the former mod was either suspended, removed their account from the mod list or deleted their account.
This Subreddit for example has 1 mod and their last post or comment was one year ago.
And
this here is an example of a Subreddit with NO mods.
I will not mention any more Subreddits like this because I plan to use them myself soon and you will have to find them yourself, the subscriber count for these Subreddits were anywhere from 1000 all the way up to 300,000, the bigger they are the more traffic there is.
How to make money?
Reddit users are very picky and strict, but who cares if there's no mods right? WRONG, you will get judged and labelled as spam.
Unless....
....you're sneaky about it.
Create your NSFW account and start building Karma for about a month, make around 10 comments and 10 posts a day, use various image hosts to post relevant pictures to your list of various Subreddits.
Next create a simple image site with WordPress and add a couple ads around the image, top and bottom, DO NOT USE POPUPS, your site won't last long on Reddit with popups and your main money maker will be with the 2 ads, but with this method you can get tons of traffic, I have investigated some users who do this and their website is top 50,000 alexa ranking. Of course most traffic is from Reddit.
Once you have some Karma and post history you can start posting pictures from your site, you can post links directly to your site with the relevant image and 2 display ads.
While posting your own image links be sure to mix it up with other image hosts like imgur so you can remain "sneaky" and hide behind that spam wall.
A single post from your site per day can net you 1000 hits per day, so don't spam and this method will last a long time.
I would suggest 10 imgur posts (or other big image hosts, mix it up) and then 1 of your posts, rinse and repeat.
The reason I suggest to build karma for a month is so that you can get the feel of Reddit and you can see which posts do well on the Subreddits you post, if you're lazy and think you can get money overnight from this method you will fail, and I hope you will fail, I believe in hard work pays off, it may take you 2 months to start making good money but by then you will thank me and thank yourself for not spamming your links everywhere. Good luck and let me know how you do.
Recap steps because English is not my first language:
1. Create a NSFW Reddit account and start building Karma for a month, comment and post images to relevant Sureddits using top image hosts like imgur, tinypic, etc etc, mix it up.
2. In the meantime find and create a list of Subreddits with no mods or inactive mods, I found 60.
3. Also in the meantime create a WordPress or image website with 2 display ads, no popups, keep images pages on your website simple, just show the picture, 2 ads, maybe some thumbs up and down button and share buttons and that's it, keep it very simple.
4. Start mixing in your image links alongside your other posts and start making money, post around 10 images from reputable image hosts then one of yours to stay under the radar.
5. Hard work pays off.
