Not to sound like a twitter freak, that's not good enough. Unless she literally told the detractors to 'fuck off and stop attacking him!', they'll take a statement like 'it wasn't a big deal' to mean she's scared by him as look how strong he is, he probably intimidated her to comply etc.

Only way to stop a witch hunt like this is to have the 'victim' attack the hunters vocally, even if that gets them to attack you..
