The issue is that Blots characterisation tends to fluctuate depending on who's writing him
In some settings he's just a wacky thief who wants to steal colour but in others his driving goal is to be a legendary crime lord and he actively wants to murder Mickey
And saying we have no problems with criminal toons is blatantly false because we just spend god knows how long trying to root out organised crime, we can't just let a new group stroll in because they happen to be Toons
We have no problems with
toons who are criminals. We have problems with toons who commit crimes on our territory.
Okay so what I'm terrified by now.
The GM gave us a tricky cipher and we used the internet to brute force it in 15 minutes.
What sort of cipher is he going to give us next time then???
If I were running a quest on a nerdy forum like this, I would never post any encrypted message without fully expecting the playerbase to casually break it.
There's an app for that, these days.
For more information, the "cypher analysis" tool picked up the string of letters as being "Vigenere cipher" except with an accented second e. I'm still not certain that is actually correct and not just a coincidence though. I don't know how cyphers more complicated than "move letters around" work.
OK, quick reference:
A Caesar cipher (supposedly invented by Julius Caesar himself) is a straightforward "move all your letters N spaces along the alphabet). Caesar supposedly used a "+3" version of the cipher, so IVLIVS* CAESAR would become LZOLZX FDHXDV.* At the time, this was a fairly secure cipher, if only because most of his enemies didn't know how to read very well, and a lot of the ones who
did would probably just assume the message was written in some obscure barbarian language they didn't speak.
(rot13, often used on the Internet as a casual cipher, is a good example of a Caesar cipher. Replace every letter with a letter that is 13 letters away on the alphabet).
In practice, obviously, it's not all that secure against a determined code-breaker who knows the Caesar cipher is a thing. The big problems are twofold. One is that every known language uses some letters much more often than others, so seeing which letters come up in the encrypted text more often
indirectly provides a clue to the number all the letters have been shifted by. The five most common letters in English are E, T, A, O, and I, so if you encounter a message in which the most common letters are H, W, D, R, and L, it's likely to be a "+3" Caesar-ciphered piece of text. The other problem is that when you get right down to it, it's not that hard to just brute-force all possible combinations for the cipher for the first five or six letters of the encoded text... and if they used a Caesar cipher, getting the first five or six letters right is usually a sign that you got the rest right.
...
You can significantly improve on the Caesar cipher using the Vigenère cipher, which is basically a Caesar cipher that uses
a different shift number each time. This is typically combined with a password. Suppose the password is BILL. We convert that into the numbers "2, 9, 12, 12." So the first four letters in our message will be shifted by 2, 9, 12, and 12 letters, respectively. For example:
ALL THESE SQUARES MAKE A CIRCLE
(first, remove the spaces)
ALLTHESESQUARESMAKEACIRCLE
(now, begin the encryption. A plus two becomes C, L plus nine becomes U, L plus twelve becomes X, T plus twelve becomes F, and so on, repeating with H plus two becomes J, and so on)

This will resist
casual attempts at decryption by hand. The problem is, if someone gets seriousface (and knows about the Vigenère cipher), they're gonna crack it pretty fast. Because, uh... BILL is actually a really stupid choice for a Vigenère cipher key.
Choosing 'BILL" means that out of every four letters in the coded message, two of them are basically just a Caesar cipher shifted by 12 letters. And, importantly,
it's always the same two. The third and fourth, seventh and eighth, eleventh and twelfth, and so on letters of the message are ALL shifted that way. This means that a seriousface cryptographer with a long enough message to work with can eventually figure out that our key was a four-letter word whose third and fourth letters were "LL," and after that it's only a matter of time before they get the rest.
A better choice of the key would be longer, offering a codebreaker fewer repetition cycles in a given coded message that they could use to mount an attack. It would also not use repeating letters so much (the Confederates used "Complete Victory" a lot during the Civil War, and I suspect that that E_E helped some Union agent break the code)
...
Rather sadly, modern computing makes it fairly trivial to crack codes of this type, unless the codephrase is so long that there's no repetition within the text of the message (e.g. using a 1000-letter keyphrase to encrypt a 500-letter message, and then
never using that keyphrase again).

*(in the Latin alphabet there were no lower-case letters, and the letters J, U, and W hadn't been invented yet, so some of the letter shifts in Caesar's time are different than they would be today- but note that I becomes L, C because F, and so on)
