I've seen a lot of conjecture in a couple of threads about the purpose of the survey, with cries of ageism and other purported slights orchestrated by Turbine. What I don't really see much of is people asking logical questions such as, "Is it possible Turbine already has enough information from my age/gender/household income/insert other specific demographic here?", or "I wonder if this survey is targeted at a group which does not, for whatever reason, include me because I'm not part of the audience they might be trying to reach with Product X/Service Y/Advertisement Z?"
What if Turbine is getting ready to advertise more on G4 TV? The the G4 demographic is mostly male, and covers mostly the ages of 18-29. If Turbine is looking for feedback that fits those demographics then are they REALLY being discriminatory? Or are they trying to spend the company's marketing & research dollars efficiently? Should I, as a 34 year-old female, get mad at Turbine because they exclude me from such a survey with accusations of ageism and/or sexism, or should I maybe use my common sense and logical brain to realize that I am the exception, not the rule, when it comes to G4 TV viewers, and that G4 TV will never gear their advertising to 30-something women? Unless a large enough group of 30-something year old females ever become G4 TV viewers - which is very unlikely to ever happen - Turbine shouldn't waste their time and money researching my group in relation to G4 TV regarding a new ad campaign.
The above paragraph is just one hypothetical example, but rushing to accuse Turbine of ageism/sexism/any other -ism, based on exclusion from a marketing survey is, frankly, an overly dramatic and victim-mentality response. It screams, "What about ME!?" Sure, Turbine should have pre-screened the players to be included in the survey introductory e-mail better in the first place, but poor marketing practices are not indicative of discrimination.
