@Cobaltasaurus I've played on Shang during different periods for shorter or longer stints. Conversely it's a fallacy you can't play unless you TS there - I did it for months and had plenty of fun. There are many pretty good roleplayers on that game, it's just harder to track them down since they're bunkered up away from the sheer insanity by sticking into small groups and filtering fairly strictly who gets in. Cliques on Shang are required if you want to retain your sanity. 
Anyway though - the pages I used to get and the things I was told completely out of the blue by people I had never even chatted with before were ... interesting. I mean for starters you know how the line we're examining here is between IC and OOC? Some players don't want it at all, and they're very upfront about this fact. The MU* is more of a chat channel to them so instead they occupy this hybrid ... space lingering between the two. I'd get pages out of the blue like "I want you to do <X> to me", where <X> could be goddamn anything imaginable, sometimes barely recognizable as a sexual thing in my book - and those people didn't really have characters, they just had a name and a list of kinks.
I'm not usually one to judge if I can help it but as I am also both unwilling to disregard the player/character separation blatantly and unable to actually do anything to people over the internet, not being a wizard, I was always left extra puzzled by the requests. Either frame them in an IC way or don't, dammit!
What I was very pleasantly surprised by when I joined KD was there was no insanity. I'm pretty sure some hefty TS is taking place - the setting is what it is after all - but it wasn't like that at all. The over-the-top frenzy isn't endemic to sexually themed games, it's contained if staff care to do so. Which is not to say other phenomena didn't occur there too - I did have people lose interest in my PC once they realized he was 'taken' for example - but that's a fairly common thing to encounter in any given MU*; sometimes romantic entanglement RP is a game of musical chairs.
