The game ends in a loss if we do not discover the phrase. I would rather begin a process that actually moves us forward, rather than blindly stumbling about until we accidentally do something right. I expect, especially in the early stages of asking questions, to not be productive in finding the insider. Towards the end, perhaps we might be able to see someone who makes odd leaps of logic, or connects the dots too quickly. Claiming that a method that actively helps us find the phrase is "not a great start" is not a great start, Condude.
You said yourself that finding the phrase wasn't a problem. It's trivial to find the phrase in... 20 posts? The challenge is to do it in a way that isn't so trivial.
Assume the phrase is "Kill two birds with one stone", how many questions does it take?
Post 1:
5 words or fewer?
First word's first letter N-Z?
First word's second letter N-Z?
Answer: No, no, no
Post 2:
7 words or fewer?
First word's first letter A-H?
First word's second letter A-H?
Answer: Yes, no, no
Post 3:
6 words?
First word's first letter i, j, or k?
First word's second letter i, j, or k?
Answer: Yes, yes, yes
Post 4:
First word 5 or fewer letters?
First word first letter i or j?
First word second letter i or j?
Answer: Yes, yes, no
We now know it starts with a k. Keep going, within about 10 posts we'd have a very good idea of what the phrase is (something like "Kill tw...")
Heck, we could play 3 games of 2-player hangman to guess the first three words. That's probably even easier. The hangman idea fails because the insider blends in perfectly.
The point is, finding the phrase isn't the problem. Finding the insider is. You figured this out, and proceeded to completely ignore your own advice. That's why I view you as a likely insider right now.
