I had some preliminary results up, but Survey Monkey alerted me to the likelihood that a fraudster hit my survey and took it over 20 times. Survey Monkey is working with me on it, but until I get those responses out of the results I can't do anything. (This also means I can't yet run the drawing for the Amazon gift certs, although those were apparently enough of a draw to lure in the unwanted fraudulent respondent.) Sucks. This person is not a modder, they are a fraud! Boo! You have been caught and will not be "winning" a gift certificate (winning in your case equals cheating). Everyone ELSE did not cheat, and I am really honored that they all took my survey.
I have used the HTML comment tag to make it so you won't see the previous and now-invalid write-up, but you can view the page source if you really want to see it. If the fraudster answered "male" every time (I don't know yet), then the male-female ratio will be severely distorted (with the fraudster, it was 33F/109M, so maybe it's more like 33F/85M).
Well, it is internet, I knew this might happen, I just didn't think it would.
Edit: Or, bummer, almost all of the female responses were from the fraudulent respondent. Perhaps the findings from this survey, once the data is cleaned up (amazing what some people do), will show that the % of women who mod is more in line with the % from the IGDA survey (10% or so, mentioned in the part I have now commented into invisibility).
