I'd dispute it in this sense: women, like humans of any gender, are more likely to apply different standards based on pre-existing status (e.g. whether they're friends already or not) but not to the degree that as a rule they'd welcome a sexual advance from one co-worker and not an identical one from another based simply on attractiveness, or that they'd consider the unwanted one harassment.
This isn't hard: women are humans and capable of rational thought, just like men. Your comment diminishes them.
This would directly translate to welcome a sexual advance from one co-worker but not an identical one from another based simply on attractiveness. Social setting (e.g. workplace) may drive the lower limit below skirting board for some individuals, but that does not make certain social settings universally irrationality free grounds where evaluation as potential mate has no effect on social (and even professional) interactions.
While both men and women are capable of rational thought, likewise both are not individuality, emotion and desires free.
Your comment reads to me as asserting that women are basically incapable of moderating their behavior based on sexual desire.
Viewing social interaction as a series of rules/steps to follow in order to "succeed" or "win" is how you view being attractive as a form of "cheating" or unfairness. This doesn't account for the other party having agency, since the only perspective taken is that of one side of a two sided issue.
Even in your post you say "women often apply different standards to men's behaviour based on whether they find them attractive or not".
Let's be damn clear: there are no different standards at play, there are two completely different behaviours at play - welcome romantic advances and unwelcome romantic advances.
How? There's no connection between what was said and the conclusion you drew from it.
arkh's post observes that women often apply different standards to men's behaviour based on whether they find them attractive or not. That's not really in dispute, it's the origin of the "hot women being attracted to asshole boyfriends" cultural cliche.
