I havent seen a single person in here running DC for Blizzard. Just because someone doesn't believe every single poster on the internet doesn't mean they are Blizzard fanboys and sycophants. Some people just want clarification which is a reasonable request to ask for since everyone's accounts are at risk. Considering every single person who has claimed on the bnet forums to have been hacked with an authenticator has been shown to have lied or added one after the hack occured it isn't such a stretch to assume people are trolling and asking for clarification is only reasonable, unless of course you have an axe to grind then it is completely unreasonable to ask for clarification.
If someone says "you can't get hacked with an authenticator cause bliz said so" then asks for clarification...they aren't really looking for clarification.
