I still think that Timbal would get a far better response in person, from someone that he knows and who can know for sure he's in college, and even speak to the professor if required.
True, but we don't know if Timbal hasn't done that yet or if he has but wasn't satisfied with the results. If he wasn't satisfied, he's well within his rights to seek other sources of material, including this forum where we all claim to be writers and creative and junk.
Over the Internet with no accountability--sorry, but I wouldn't want my characters infringed upon that way if the explanation turned out not to be the truth.
So create a throwaway character. Go look at the survey. It's not like you have to write a ten volume character bible. Make up a name, pick a bumpy fore-head alien, coin flip for a rank and answer a couple of geek questions. As far as I can tell the survey itself is anonymous, so if you do make somthing up and you find out the guy's actually drawing kiddie porn, the character itself can't be traced back directly to you. Just don't invest your entire store of emotional karma in the character.
And anyway, am I the only one who finds it just a bit dense for us to be so worked up about protecting characters set in a universe NONE OF US LEGALLY OWNS? Seriously, suppose CBS Paramount issued a press release stating to the effect: "All you fanfic authors are now required to pay the piper. Either you pony up the standard literary licensing fees or all your Star Trek OC's are now belong to us!" Are you all seriously going to try to tell them "Well you have no right to take my original characters because I poured my heart and soul into them!" How long do you think Paramount would laugh their asses off before a judge told you to start writing checks?
Timbal is not asking for your life savings. All he asked was that you fill out a survey. We don't have the full story on why he's asking, but let's not immediately jump to the conclusion that helping him out will lead to hard time in OZ or cement shoes.
