It is enough to search for a pornstar's name to find porn in the Reddit app. This works even if you don't have an account and NSFW content is disabled. While it's not as "simple" as a porn keyword, it is almost certain people do this. Reddit relies on people tagging their content as NSFW, but of course this is not something they can enforce 100%. And once you find an account posting NSFW, you can access all their NSFW posts even if they were made on subreddits that are hidden to you if you search for them explicitly in the search bar.

By the way, when I typed the actress' first name, I was already being suggested a subreddit dedicated to sharing nude pictures of another woman with the same name. Again, I used the app as it comes straight out of the App Store without logging in or changing anything.

open a browser, navigate to https://www.reddit.com/r/tits/, click yes, done!

Holy shit. Since when is there naked women on the Internet?

When I go to that link (on iOS), my only option is to “view in app”, which is a shitty option to offer.

PWAs would free them from having to put up with Apple’s restrictions crap.

Apple knows this, hence why they've not implemented the features needed by PWAs, and why they ban all browser rendering and JavaScript engines besides iOS Safari's.
