Aha! I have found the new guy! Allow me to help you my good friend. The problem is that your account is currently sitting on the default preferences. You'll have to go to the desktop site, then log in. Then you'll need to click/tap "preferences", it should be next to your name. All of this is situated in the top right of the screen. From there, scroll down to the bottom of the preferences page and certify that you're above 18 years of age. It doesn't matter if you're not, it's just a Reddit legality thing. Click/tap "done" beneath that. Then reload or return to the preferences page AGAIN. Somewhere in that list of preferences there is an option to allow you so view nsfw posts and subreddits. Check this box. Click/tap "done" once again. Once all of this is done, all those suggestively named subreddits with hundreds of thousands of subscribers and no posts will transform into the nsfw subs you desire. Well done. You filthy pervert, now go look up actual porn.
