There are many possible explanations, but the following seems most likely to me: The hidden message is from GEOTUS to his clued-in fan base. Franklin Graham sends him a letter, then GEOTUS has someone reproduce the letter exactly as it was received but tinker with the font ever so slightly to hide a message. It is essentially just a "wink" and a morale-booster for his fans who look for comms. It also might also be done to give us some small sense of what will happen in the future. Just a pet theory...
