Again, that's part of my 'COMMUNICATE WITH EACH OTHER' hope/mandate/hammer to the forehead. I don't want to ban topics (I've already been round the bend twice with the MES and their recent 'you can't have <X> topics as a backstory/thing to play out' policy that came about because, well, the MES is a joke and won't eject people who are PROVEN to be crazy), especially if people are comfortable with them. And I don't want it to be a way to get out of consequences for things like, say, attempting to assassinate the leader of the city's supernaturals or the mayor or being a moron and getting the police on a manhunt for a murderer.
But if Player A says 'I'm a monster, I want to <X> to your character for <Y> reason' and player B says 'I'm game' then that's consenting after communication, and you have communicated per my personal 'cooperative non-consent' game policy/ideals. Conversely, if player B says 'I'm not comfortable with that, <Z> is a better out come for me' then that's fine too. And in both cases, if Player B says 'I don't really want to RP it out, it's fine to DO but let's FTB because... well, I can deal with the aftermath but I squick writing it' or whatever, then that's fine too.
But if Player A is told no and player A continues with that shit, that's where staff should come in. As far as your experience with the rape plotlines, I haven't had any experience with that personally. I've done the whole capturing, torturing, murdering stuff but I don't enjoy sexual RP. I have heard about things, so we'll see how things go on my game. I'm talking about policies from my own personal standpoint, so YMMV.

Hence why I brought it up. I feel that it's something that HAS to be adhered to, simply because someone may be cool with the OUTCOME, but... it doesn't have to be 'on screen' for lack of a better term.
