When it comes to torture, there's actually a lot of argument on how well that works anyway, since the person is going to tell you whatever they think you want to hear rather than anything resembling the truth.
It was a point that was brought up to me while I was playing a character that later went on to become an interrogation specialist. Still one of my favorite characters because people hear the term "Interrogation Specialist" and picture a large brutish man with self inflicted scars and a fetish for some sort of pain... but then in walks this cheerful, friendly person who just seems mildly disappointed in you.
The person who trained our team ICly had a player that knew his stuff when it came to interrogation frighteningly well. We still always did two person interrogations, but it was never good cop bad cop. It was "good cops vs bad world." If you want good information you don't scare and torture the person, you earn their respect and convince them you are both just stuck in a bad place. You understand why they did what they did. If you were there, you'd do it too, but that doesn't change the fact they did it. You want to help them, because you know why they did it, but if you're going to help you need to know every single detail as accurately as possible, so that the other guys can't poke holes in your story. You are putting your credibility and career on the line for them, they need to help you.
His approach worked almost every time, and there was no OOC conflict of "that didn't work" because they didn't have to resist anything. We weren't rolling to make them do things. I know torture is dramatic and cool... and some people don't have the patience to do three days of scenes of being amicable with a serial killer but it works, and in the end makes pretty fun RP to me.
As for seduced against the character's will, I have had people roll the seduction at me and let the results stand no matter how I felt about it OOC, since there's a mechanic for it. I just also fade to black to scenes.)
