@Scribblemonk Just double-checked (thought it was in there) the ToS that pops up literally every time you start the game no matter how many times you've scrolled through and clicked "accept" and yes, it's in there. Posting vulgar, profane, and/or pornographic content of any kind is a violation of PSO2's rules. So, yea. aside from being pointlessly immature, it's also grounds for being banned from the game.
I don't "Stress over it," but I don't just ignore it, either. People need to follow the rules. It's not fair that other players should have to explain to others in their household why there's porn in the game (when there shouldn't be) and it's not fair to streamers and other content creators who have to curate or outright throw away video content or risk getting banned themselves because some selfish jackass can't follow simple rules.
I look at it the same way I look at hackers, spawn campers, and other such filth in the gaming community. They're self-centered pricks who think THEIR enjoyment is all that matters at the cost of everyone else. They have no place here.
