You seem to be confusing high-status creep and low-status creep. The latter, which you describe, happens among desperate low-status men (rarely other genders), is characterized by misogyny and a sense of thwarted entitlement, is obvious to outsiders, and makes then even less desirable partners. Hanging around women is usually promoted as a cure, and looks like it works. I see little evidence for or against this being evolutionary or cultural.
The former happens among predators, who often (not always) are high-status because they're driven to be, is characterized by a sense of entitlement that is denied but acted on (by flouting norms and personally-imposed boundaries on interaction, especially sexual), and works in the sense that it gets the creeper lots of dubiously consensual sex while avoiding social blame. This seems to be a straightforward outgrowth of "Screw the rules, I have status".

Also, placing a male into a high status position probably increases the chance he will exhibit this behavior.
One of the lessons highlighted in the thread "Less Wrong NYC: Case Study of a Successful Rationalist Chapter" is Gender ratio matters.
There have recently been a number of articles addressing one social skills issue that might be affecting this, from the perspective of a geeky/sciencefiction community with similar attributes to LessWrong, and I want to link to these, not just so the people potentially causing problems get to read them, but also so everyone else knows the resource is there and has a name for the problem, which may facilitate wider discussion and make it easier for others to know when to point towards the resources those who would benefit by them.
However before I do, in the light of RedRobot's comment in the "Of Gender and Rationality" thread, I'd like to echo a sentiment from one of the articles, that people exhibiting this behaviour may be of any gender and may victimise upon any gender. And so, while it may be correlated with a particular gender, it is the behaviour that should be focused upon, and turning this thread into bashing of one gender (or defensiveness against perceived bashing) would be unhelpful.
Ok, disclaimers out of the way, here are the links:
Some of those raise deeper issues about rape culture and audience as enabler, but the TLDR summary is:
EDITED TO ADD:
Despite the way some of the links are framed as being addressed to creepers, this post is aimed at least as much at the community as a whole, intended to trigger a discussion on how the community should best go about handling such a problem once identified, with the TLDR being "set of restraints to place on someone who is burning the commons", rather that a complete description that guarantees that anyone who doesn't meet it isn't creepy.
