About Security Measures Taken at Blizzard, or Hello, Tree

Being on vacation and not knowing what to do, I decided to run in Diablo III.
Not here it was! Blizzard had other plans for this.

So, as an honest person, I went to battle.net and bought a Russian license. Then the fun began:

Your *** account is temporarily blocked due to a number of suspicions. To unlock it, please do the following: [...]
3. Change password
To use your Battle.net account again, you need to change your password. To do this, go to the following link:
eu.battle.net/account/support/password-reset.html

So, buying money for Diabla from an existing three-year account is a series of suspicious actions. Fine, I think.

')
I'm going to change my password:

We must make sure that you are the rightful owner of the account ***. To do this, you must perform one of the following "test" actions.
Select a verification method:
- Answer the secret question for your Battle.net record
- Indicate the first 6 characters of the game key for any of the games assigned to your Battle.net record: World of Warcraft, The Burning Crusade, Wrath of the Lich King, Cataclysm, StarCraft II: Wings of Liberty, Diablo III.

The answer to my secret question is filled with a random one, since I consider this method of account recovery a security hole (you cannot choose your question there, and it is easy to find the answer on any of the standard ones knowing my account on any social network).

Okay, we go for the key:

Hello, ***! Blizzard Entertainment thanks you for your purchase.
If you made this purchase on Battle.net (and not in the Blizzard online store), then the game is already attached to your account.

The fun doesn't end there. On the key registration page it is written:

It is necessary that the key of the game was registered at least 3 days ago.

Total, the logic of morons from Blizzard is as follows:
1) if three years as a registered user has just bought a game from his usual ip - he has committed a series of suspicious actions and should be blocked;
2) to unlock, he must wait three days, then go in some way into his locked personal account and copy the key of the newly purchased game from there; It would be particularly interesting to find out how, according to Blizzard, it increases security - if someone broke my account, then he also got access to the keys.

It's just some kind of apotheosis of idiocy. I stocked up on popcorn and wait for me to answer in support.
PS Admins, why did you remove the blog "Idiots on the wire"? Now would be useful.
