with no response from Blizz

Blizzard is notorious for not responding to stuff like this. When Pursuit got banned they wouldn't lift a finger- even though it was a non-intrusive program (it was basically just OBS on the client side) that had already been approved by Blizzard and used by OWL teams. So why would GamerDoc expect special treatment?

Generally miffed that the information provided to Blizz has not been actioned.

Blizzard bans cheaters all the time- in fact they just announced a ban wave a few days ago. GamerDoc himself announced another ban wave last month, so I don't know why he's pushing so hard on this narrative that Blizzard does nothing when that clearly isn't the case.
