@Ganymede I don't think it's as hard to draw the line as it sounds. In a non-consent scene, if a pose or emit would detail graphic harm done to another character, or describe sexual or non-sexual torture or assault, could just state that it's going FTB before that pose or emit is said. And then players can state if they'd all prefer to proceed, and go on as normal.
Say you were gaming with an underage gamer, and there's a point where the scene would get uncomfortable graphic. I think most players would say, 'well okay it's going this way, so we'll handwave it and this is generally what happens' in an ooc explanation.
Mind you, I just ban all sexual assault storylines. It's just not permitted, and that's understood, because I don't want to have to spend time sorting those. If staff wants to permit it, that's fine, staff can and should do whatever they are comfortable with. I'm just saying that almost every game I saw that said, 'well okay we'll allow it and just leave it to players to set boundaries', I've seen threads pop up over some huge blow up specifically over this. And I think that a, 'default FTB' is probably a wiser course that would avoid that if you don't want to ban it all together like I do.
I also worry that we can easily forget how petty people can be, and how much they really want to see their 'enemies' on games get what is coming to them. An awful lot of people want their opponents to RP out scenes uncomfortable for them. Embarrassing and humiliating ones. I have, on at least 4 different occasions, seen people complain that someone not playing out some kind of torture or punishment scene as trying to avoid the consequences in ICA=ICC. Even if they would be fine with taking it in a FTB. No, they want that player to be upset. Wanting to see a character in an antagonistic relationship be publicly humiliated and punished IC is pervasive, and that can go way too far way too fast.
