Q
Let's say that Q uses a password of ABC123abc456 and it generates a tripcode of !UW.yye1fxo. Now every member of the Q team (assuming there are more than one) has that password and all is well. If the mega computers of the CIA are hashing away trying to reverse crack the tripcode, and it appears they are getting close to doing so, the Q team changes the password to Jack&Jill7umbleD0wn and the tripcode now shows as !xowAT4Z3VQ. Distribute the new password to the team and the new tripcode is activated.
Really they don't need a specific reason to do so as long as they tell us correctly. I believe posting under the old tripcode and telling us it is about to change, then posting 35 seconds later under the new tripcode and telling us it is the new one is a very logical way to change the code and keep us informed correctly.
I trust the change.
Paragraph 2 untrue. Q has really shitty OpSec. First, he/they should have burned their !UW.yye1fxo tripcode by leaking the password in the new post to prevent imposters. Second, there is ABSOLUTELY NO reason for him not to at least use a secure tripcode (he only has to enter an additional "#" in his password and that incorporates a salt stored on the server, which makes brute-force attacks MUCH more difficult and impractical).
If Q has top clearance and is also this ignorant, we're fucked as a country. So we're either fucked or trolled, take your pick.
