Might be unrelated in this example, but when a message is written in a lazy ROT13-like cypher, the letter e becomes a notorious rat that allows anyone to break the entire thing in very little time.

Randomizing/obfuscating the letter case might buy you a little time, though I think it's something else entirely here.

ChatGPT was able to decrypt this in about 12 seconds with no context, which I found interesting.
