In all my relationships, my best friends have heard every detail of what goes on, good and bad. As for the ones that have ended, I could never ever date the guys my best friends have dated. My best friend's ex treated her like shit and still does, and my best friends have heard all the obnoxious things my ex did, so there is no desire for any of of them to ever date my ex or me to date their exes. If we had dated casually it would have been different (my ex is a boy that my best friend "talked to" for maybe a month in high school then decided she didn't like him), but when you spend a year or two with someone, they become like a brother to your best friends, someone they could never dream of dating, and they just hear way too much about them to ever want to date them.

As far as acquaintances and sorority sisters I'm not that close with, I would probably stay away from guys that were in serious relationships with an acquaintance. If they casually dated (not exclusively) or hooked up once, I don't see a problem there. It drives me nuts when girls think that every single girl they know should stay away from a certain guy because they hooked up at a party one night. One girl in my sorority flipped on another girl for making out with a guy that "she saw first and thought was cute", which the other girl hadn't even known....That's just ridiculous.
