While we sometimes don't take issue with members posting the occasional survey to help with their classes or whatnot, it's more of a "courtesy" we allow to existing, active members.
You showed up a few years ago, posted a similar survey to help with your Masters, then disappeared. No thanks, no follow-up, no anything. Then you pop up again the other day for help with your PhD, recently bumped a thread from 2005 for no particular reason, and will likely leave again whether you get your info or not.
Sorry, good luck with your research, but the forum isn't a bowl of guinea pigs. (I don't know if "bowl of guinea pigs" is a thing, but it should be.) Want to participate in regular discussions like a non-trolling, non-spamming human being who shares knowledge when it's helpful and doesn't just serve your own interest? Cool. Want to use the place only to further your own agenda whether that's educationally, professionally, or personally? Not cool.
