An interesting question would be if those men which did the wrong thing were regulars to these conferences or new to the scene? From similar things I have been to I just couldn't imagine a community in which the core regulars would have anyone doing these kinds of things.
I'm Mackenzie in the article. The guy who made the comment about why someone else was agreeing with me...he wasn't new. I don't know about the guy who grabbed/kissed me.
Going a little broader in the tech field... I know of some people in the hacking/security community who are...well, when you're new to the scene, you're warned about them. I can only think of one guy I was warned about, but he's well known. I can think of two others I was told new guys to the scene (particularly if fairly young) should be warned about, and those two are around-since-phreaking-days levels of established and well known. Being icky doesn't mean ostracism.
Have you met any of the "core regulars" in the Linux community?
The short answer is that the people who do these things include both regulars and newbies. I have personally been groped or fondled by two "core regulars."
