For everyone cautious about Q's latest posts actually being Q, here is something to consider:

Q confirms posts by Trip Codes. The content of the posts are validated by either 'Future proves past' in news articles or Q will update and confirm a Trip Code (ID of poster) by handing off validation from one ID to the next through replying with prior code to new code.

Q's current Trip code is: !!Hs1Jq13jV6

This code was confirmed on Dec. 2, 2019 on posts 3639, 3640, 3641, and 3642.

Q has been using this same code since that date and this is the same Trip code used in the new posts yesterday!
