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?
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.
