Although, with that guy's track record, maybe he knows being a cocky asshole is just the way to get a good job in software, I don't know.
edit: after thinking about it more, I think this may be a parody of the sort of unrealistic expectations recruiters have for 'talent'.
These comments sadden me. I work with Ken at dotcloud and can tell you he is one of the most humble and easy to deal with colleagues I've ever had.
Have you never been contacted repeatedly, almost to the point of harassment, by a recruiter who wouldn't take no for an answer, yet could not be bothered with even the most basic research about you?
It's that combination of a) blind persistence and b) disregard for the actual person that defines truly spammy recruiters, and which obviously drives Ken crazy. I don't blame him for trying to stem the flow. If anything I would like to find out if this new anti-spam tool actually works :)
I mean who here hasn't been contacted by a recruiter asking about a skill set you barely know or don't even have on your resume? Or their understanding of it in general is so far off you don't even want to deal with it? Or ones where they try to connect to every person in your company through you? I could go on and on. It gets maddening.
I know multiple people who have taken this strategy and learned that "unrealistically high" wasn't. By and large they regretted that strategy. But hey, at least they got paid for it!
