I'm going to tell you the truth about the "scandal" and I've been following it from the beginning, before this thread was even created. Keep in mind I've posted about Sam ITT a lot and have been called a liar many times but in the end I've always been proven right: the only thing Sam did with Marky that could be considered wrong was the age gap between them if they actually did hook up (which neither party has ever confirmed). I don't remember what state it happened in but the age gap was legal wherever it was. So no crime was committed whether it happened or not. Ethical and moral issues aside, I'm just saying the facts. The only truth in the Marky "scandal" is that they may have dated and hooked up.
All the other stuff like rape and beatings never happened. The bloody nose was a gag - which Marky herself admitted to. Sam does casually lie a lot, as we all just witnessed with the "she told me she had a knife" tale, but Marky said the blood stuff was a joke, from a time when he was putting women in choke holds and stuff.
The "scandal" seems bigger than it is because Channing, herself, has been posting it around various communities using various socks for a decade. She is a known liar and there's a hundred pages or more of this thread where she's getting exposed for lying. Sometimes she tells the truth but greatly exaggerates it or leaves out critical details intentionally so she really can't be trusted either way.
That's the scandal.
