So, in this game, you look at the above poster, and observe things about them in their signature, and side bar, before coming to a conclusion.
The poster above has few posts for the amount of time he's been on the forums, yet the name is well known. That means he must post a lot in the Fun and Games section, or went on a hiatus at one stage. His signature shows links to his latest mafia, and other things related to Roleplays.
My conclusion is that the above poster probably posts in the Games section most of the time.
The poster above's avatar is fan art of some anime. Her userbar is in Japanese. She has been on the forums for not very long, but her name is familiar. This means she posts in widespread parts of the forum. Her signature is a banner sporting anime, and links to her DeviantArt and Tumbr.
My conclusion is that the poster above probably posts all around the forum, and enjoys drawing fanart.
