What is the easiest way to grow your new subreddit subscribers

Hey guys..I created my own nsfw subreddit about a week ago and since then I have been able to gather just 16 subscribers.I have tried every means best to my knowledge but nothing seems be working.
Please if you know about any technique I can use kindly help me out.cos I keep seeing subreddits with thousands of subscribers and I wonder how they were able to achieve that.

I've been wondering the same thing.

you can try joining upvote circles/skype groups on this very forum, so your posts can get more visibility (not by the upvoters, but thanks to their upvotes), some of your posts may even go viral, that's how you can gain subscribers fast

btw NSFW niche, have you tried gifs? make a few in your niche, try to mix it in with regular posts and see which performs better

there's a tool called screentogif, which can make gifs from anything which plays on your screen, it works pretty good and it can make awesome quality gifs relatively fast depending on your config, however you need to mind the upload limit, which is 3 MB for gifs

I'm facing same problem and need same help. I'm now waiting for next comment about acquiring knowledge about it. Thanks for your post.
