They could just easily stop offering the service and not have to deal with it all. Thankfully they have not yet.
But they aren’t dealing with it at all. Hundreds if not more people who have never botted/cheated are getting swept up in these bans. And to make it worse when they try to reach out and find out what’s going on they are finding themselves on the receiving end of accusations and mistreatment by support and some other players on this forum. Very sad state of affairs for classic battle.net. I have since moved on to some S19 D3 and the new 3.9 content for PoE… still kind of bitter though I had a level 73 Hammerdin with Spirit sword and shield a I had just built a smoke armor. Also, all of the loot that I had found that wasn’t something I could use specifically for this character I was joining some random open games and giving it to other players (in the spirit of the holiday, of course). And how is my kindness repaid? With a ban. Good stuff.
