I point you to this very FRQ thread, circa 05/2021:
The original "B" post, #111 on ..projectdcomms.., named Q-drop 4954.
I need to remind you that the "B post" had a masked IP of "000000"
https://freerepublic.com/focus/chat/3963110/posts?page=467#467
Where did it go?
The better question is where did it come from?
Now, look at the timeline on QAnon.pub.
Herein, I have reproduced the work of several Anons in determining that drops with IP mask "000000" are fake and generated INTERNALLY to 8kun.
It was an 8kun INSIDER generating the posts.
