I've already opened a ticket about this (closed now) but if we're gonna just do it manually then it's going to be quite the long list. So here's what I'm suggesting...

Since the issue here is TMDb's definiton of what constitutes an 'adult movie' (most of Tinto Brass' filmography is not marked as such, while most people would describe his movies as "porn but, like... with dialogue") a middle ground can be found in the tags of these movies (which makes them appear in the recommendation sections and search). So while, say, Beneath the Valley of the Ultra-Vixens is not marked as 'adult movie', it still has 'sex', 'explicit sex', 'erotic movie' in the tags.

The problem is that some of these tags are used by legit movies like Shame and 50 Shades (though there's an argument to be made there lol) and blocking the movies based on tags could mess with people's libraries. So i'm suggesting again an option in user settings for those of us who want to just omit them from search and suggestions and any other place they would appear, and if one clicks on one of their links a page would tell him that this is an NSFW movie.

I still think this feature should exist at least to be enabled by default for underage users.

I'm only posting this again because it's surprising how often one encounters these movies even when they don't seek them out, You'd be looking at a european movie (most of them contain nudity, occasional sex scene) you scroll down and here's 5 softcore porn suggestions.

An alternative suggestion is to make the recommendation engine ignore these tags in its process.

I'm not a prude or anything, it's just something one would rather avoid if possible, would you agree?
