If this is about GDKP in SOD, this has been announced in advance here:
As it is Blizzard’s private property they may ban for any or no reason, in this case its a ban for violating the TOS. Receiving a templated answer does not make it an “AI answer” as long as the ban is upheld they simply don’t need to give a different reason.
An appeal is not to give your “proof” but just for a fresh GM to review the evidence Blizzard holds and see if an error has occured or not. They may continue to appeal until they will honor no further appeals.
You’re free to consult consumer organisations should you think your rights were violated.
The proper analogy is:
The customer is dining at a place but cannot behave and is asked to leave. Leaving behind the food have otherwise paid for and would’ve eaten if they didn’t violate the rules.
Its private property and they may ask anyone to leave for any or no reason. Just like the previous example, a reason was stated that the customer disagreed with.
