Blizzard turning criminal?

It doesn’t need to be mentioned to resemble what is defined what is banned currently in SOD. Which you can read once again here:

No scam occured. If you broke the terms that comes with accessing the service that’s on you if a penalty falls that way.

Cannot be stealing either since you do not own Blizzard property and they have your permission and therefore right to withdraw from the contract for any or no reason.
