This question is related to my same question for WoW. I promise that it's the last. I have all the answers for other games. WoW and SCII was the only 2 missing.
Is there a way to prove by any way that a special character is really owned by a player.
I explain myself:
On a website, users can add their SC2 account to show their statistics on the website.
How to ensure that the user on the website really owns the account (and is not "stealing" statistics from a really good known other player) ?
