Looks like assembly. Also, the "inputs" (ex: 083 112 097 109 032 097 100 100 115) look like they could be ASCII representations of characters in decimal, but I doubt Sub is getting anywhere with these.
Ironically, the example that I provided says: "Spam adds." I shall translate the rest in a second post.
From OP:
First quote: "No"
Second quote: "> Q ` M P"
Third quote: "Spam Adds"
Fourth quote: "O e k h W b b ] W O"
Fifth quote: "H l a ` b j"
Sixth quote: (I assumed that he was spamming the "add" function instead of providing an input): "K i l l H i m."
Essentially, Sub's being a complete idiot. I wouldn't be surprised if he's trying to make some kind of silly ARG using a minimal knowledge of assembly - I bet if you run the "garbled" messaged through some form of caesar cipher or assembly compliler, they would provide a "real" message.
