More a hidden message to decipher that a easter egg but you got it right, for see it better i suggest to open the imagen in another bowser page, the compression is a little bit odd and blur the fine text. Anyway before i forgot again, I should thank you for the possibility to "publicize" my socials, but i don't have any (at least public) for now, it's just my hobby and at the moment I'm content to share my work only here, but thanks again for the opportunity
Understood on the socials then, no worries.
And interesting. "319720IT".
-It is not a valid actual cattle tag ID, as convention places the letter FIRST, and only one letter, not two.
-It is the same number of characters as "Bitshift", and ends in the same character. This might be the encoded string, but how do we get there?
-It cannot be ASCII encoding, as the "IT" would be nonsensical: ASCII is denoted in hex, and i and t don't exist in hex. It's also much too short if we're aiming for "bitshift".
-The obvious joke would be to use some kind of shift cypher (hur hur), but the combination of letters and numbers, and the fact that the "t" at the end appears to be unencoded (or at least "drop through") throw wrenches in this. At the very least, it's not a SIMPLE shift cypher, where we're just shifting everything x characters in the alphabet.
-Discarding "bitshift", if we convert the numbers into letters assuming a = 0, that gives dbjhca. If we then multiple-shift in sequence 1, 3, 25 every two characters, this gives "cagedb", which added back on to the letters gives "cagedbit". Which is somewhat sensical give Mezz's new decoration, but I only have moderate confidence this is the intended string; this feels less like a decoding and more like I'm practicing numerology.
That's my guess so far though.
