So i just noticed this thread (and your pm) as I have not been on the forums for a while. I am not the guy you are looking for I am afraid, though that is my flickr account and I am a technical guy. The 20btcs you are talking about came from http://bitcointalk.org/index.php?topic=588.0 . Hiroe is the one who sent them to me, I do not know Hiroe outside of that single transaction. Hope that helps in someway.
