Contained within your analysis is the proposition that Reaper employs a variety of methods to refute speculations about her. This creates a dilemma where it is impossible for her to disagree with your portrayal without the specious appearance of affirming its entirety. Contrary to the belief that she will not acknowledge she is wrong, I have seen her display a Socratic respect for uncertainty as well as integration of external insight...within contextually proper discussions.
Many people here make the mistake of taking many of Reaper's statements as sincere reflections of her sentiments, despite that she is a self-professed pathological liar and troll who enjoys being the center of attention. Combine those elements with with her interests, and you have a dynamic where through a mixture of honesty and baiting, she assumes center stage—to her entertainment. The hook is her proclivities, and the lures are her ambiguities, threats, and etc. The lures are effective to the point that Ed just used the term "TK hating bucket," and Inquirer once advised a new forum member that all one needs to integrate into the community is make fun of Reaper in the chat. Personally I find it comical when 7-8 people are in a chat room trying to convince her she's wrong about herself, and undoubtedly she teases that process along. Fun for everyone in the end, I suppose.
I agree that the talk about murder gets a bit redundant at times, and that her comments do tend to be about herself. That aside, I am also in agreement with what much of Ed said, and I think the general consensus about her is a bit poorly framed.
