I'm fairly certain data is encrypted during transmission. In the good ole days packet sniffing was easy but most publishers caught on to that a long while ago. The data probably uses a generated hash. If you made a tool to send the packets (data you wanted) without the correct hash, it would be rejected.
Ah I see, well I'm not very experienced in web development so I'm not certain of how to find the correct items needed. Do you perhaps have any ideas in mind to try? Modding Destiny through PS3 is absolutely useless, so web exploits should be the only way unless we're talking NULLing out demonware strings to avoid bans.
