Yes, and imagine hackers wanting an easier way to gain access to someone’s account. No, I am not accusing you as being a hacker, just using it as an example. There is a reason why Blizzard can not assist your friend through you, she’ll have to deal with this herself. This was mentioned by Vrakthris previously in the other thread:

Sorry, but nobody here can help her through you, including any Blizzard staff.
