Generally customer support uses templates. This is industry-wide and not considered Blizzard specific.
They clearly are. Often players hide details about themselves to make their case look good but Blizzard can see a surprising amount of details about your account. For good reason.
I notice that you’ve moved the goalpost from several days, to one week. You’re being rather inconsistent with your assumptions.
You dodged the linked threads evidence that disproved your point and were unable to provide a counterargument.
I’ll finish with that:
Attacking or assuming things about me personally is not a counterargument.
A meme is not an argument. Hearsay is not evidence of anything. Don’t believe a random redditor, youtuber or whatever that only keeps rambling on without showing you actual evidence.
Peruse the below two previous linked threads that are similar to your core worry of the behaviour warning at your leisure and wonder why they didn’t come back to create a “I’m banned after a behaviour warning” thread.
I may also add, a behaviour warning popup is not required for Blizzard to immediately levy any penalty. So the entire rambling around it is kind of meaningless.
