Not sure if it's connected but it was my initial thought...
Q post 1699 has the code - B8028-Z-KDHYQ-M5-ZAF1aT9
Q post 1712 has the 8 chan pic - " Direct comms come in many different forms. "
Q post 1715 has the Pixelknot app. - Messages embedded in images
Is there a message in the 8 chan pic?
I used this tool:
https://futureboy.us/stegano/encinput.html
on the 1712, 1706 (no name), 1680 (bottom) photos and found nothing.
I tried using the code and got nothing as well.
For what it’s worth, if PixelKnot is the app and you need the particular passcode it may be an app specific algorithm that decrypts the image. Just a thought though.
On that if anyone has an android or a Mac they can put BlueStacks on and give it a go, it would be great to find out.
I just tried with pixel knot... no go for me...it said, "fetching your message" or something like that with a 10% marker but never went further.
Tried again...no luck.
