So if we are all adults and IC rape should be handled by IC means, then I could...say...
Create a character and, over time, focus on law and police contacts/allies and a broad collection of IC patsies that were willing to take the fall for me. While harvesting xp and spending it for the top weapons, physical and combat stats, and an IC army of bodyguards, my character could then, feasibly, rape every single character on grid and use my army, money, contacts, and Allies to either derail the investigations, avoid jail time, send one of my posse to jail in my stead, and through dice, roleplay, and theme, perform these roleplay acts against anyone willing to scene and/or unwilling to log off despite how fucked up the scene is.
...ugh, I felt weird typing that. I would never play that character, but I feel it is an accurate example as to why some things simply can't be held to "ehhh keep it IC" standards.
Staff has a responsibility to protect their player base from predatory players, and the only way to do that is to establish expected guidelines of roleplay, conduct, and some realistic trigger rules.
