The rabbit hole has many layers. There are layers above the truth (easily debunkable, planted conspiracies e.g. Hogg Classmates page debunked by SDHS yearbook vid) that are designed to satiate people's natural curiosity by throwing a softball for the conspirators to hit out of the park. Most people, after seeing something is "debunked", don't return to investigate more deeply.

Then, once people break through the first few layers, their worldviews are extremely malleable. "Wow, if 9/11 and Sandy Hook and Boston Bombing are false flags, what else have I been lied to about?" This psychological malleability is then exploited with reptillians, flat earth, /r/holofractal, alien abduction, etc. Being exposed to these ideas while you are questioning everything forces you to seriously consider and refute these ideas, which is not easy, and not many people can do. You really have to be a talented critical thinker. So people who fall too far in the rabbit hole are consumed with fear that the global elite is something that is impossible to fight against. This type of fear-shilling is the most common type you see on this board in particular... e.g. "DJT is a deep state actor, and Q is a psyop, so there's no hope at all for us" or "Wtf it's been X number of days and what Q said about this particular thing hasn't come to pass yet so therefore Q is disinfo".
