I don't think I've ever been so fucking furious at roleplaysecrets. This (Warning: Potentially triggering)explains it better than I ever could. But basically? Smut RP is a sex act, albeit a non-physical one that doesn't usually mean anything. Pressuring someone who doesn't want to do it with you into it? Not acceptable, even if that someone doesn't come out and say 'no', because you should have established their interest ahead of time.
And blaming the victim, using language identical to that used to minimize rape victims? So not acceptable.
