Hey, welcome to the game fanganga and MissTake!
What are the rules on looking stuff up? I may have to withdraw some of my questions.
For this game, it’s all from your very own head. Only the Asker gets to check to be sure of the facts for the person in question. Everything else is from memory.
Officially, it’s forbidden.
Personally, and the way I play, research is not allowed to solve the puzzle or answer an IQ.
It can be allowed to ensure a correct response to a DQ.
Once in a while, when I’m “it”, I’ll get a DQ I don’t know the answer to, and I’ll look it up to ensure I give the correct answer. For example, one time I knew my person was born in the midwestern USA, but I got a DQ of “Born east of the Mississippi?”. I had to look up the exact birth location to be sure of my response.
ETA: What he said.
My specific question is that I did a bit of research in posing my two IQs - one to make it more specific, and the other to a: double check it was the guy I was thinking of and b: make the IQ less google-solvable. If that’s against the rules, I’ll withdraw them and submit replacements.
I’ll tell you what they told me when I did: it’s okay for now, but don’t do it again. 
I concur, now that you know better.
IQs:
Are you Earl Hickey’s slow-witted younger brother?
Are you one of the villains of the Balkans wars of the 1990s?
Did you, in playing a Dickens character, land on the cover of Time magazine?

IQ2: Did a spider allegedly inspire you to keep trying?
IQ3: Did a country quartet wonder whatever had happened to you?
