Sure, if you want to think a pedo who wanted to kidnap or molest or kill JonBenet stopped first to look up on Edgar the insider postings, go right ahead.
I just think that's bull. Several adults in that household had a pretty good idea what the round number was.
So they used in a ransom note to throw suspicion off themselves. They were too clever by half. I don't know what the killers motivation was, it may have not been a pedophile killing, but an old fashioned revenge killing made to look like a botched kidnapping (which would implicate JR, in that he knew who and why). I just don't think it was the parents in this particular case, anymore than I thought the Van Damms were guilty of killing Danielle. Have serious doubts that Karr is the killer also, based on the ex-wifes alibi. It's a curious case.
