That's a good point. I use twitter primarily for adult content and still get ads.
I've never consumed NSFW content on a NSFW sub on reddit. I do however run into NSFW content all over the site on random posts across reddit. Some much more NSFW than others. I wonder how they will define that content.
I'm a new twitter user but I have literally never seen NSFW content on twitter other than occasional war clips from Ukraine. I mostly use twitter for financial info. Compare that to Instagram where you just get bombarded with it.
That is my experience as well. On twitter I don't see adult content without looking for it specifically vs Instagram pushing me in that direction. Reddit will expose you to nsfw content but there are big differences between recommendation engines pushing you in one direction and the different ways you can consume reddit as a user.
r/all, frontpage, only following niche subreddits, only following your city's subreddit, only nsfw content, only gaming subreddits, only memes pages, only gardening etc.
