Sure but I can see why “NSFW” doesn’t necessarily mean “things that can upset people” or “everything undesirable.”
For instance, it’s a perfectly reasonable thing for a table to go “we don’t want romance in this campaign.” I’m not saying that’s a game I want to play, I for one enjoy a good love story and I’m always rooting for my character to fall in love, but if that’s the story the group wants to tell…well, they don’t have to! It’s all about communicating that at the top and everybody agreeing, or identifying something during the game and having an open discussion. Odds are unless you’re truly with a group of random people that you’ll find a game that works for everyone.
