It failed because, based on the evidence I have submitted to the national authority for data protection (the national entity enforcing the gdpr), they were not able to rule in my favor. In the e-mail exchange between me and Blizzard, they declared they store process data anonymized, but I don't believe it, since based on that data they decide to ban real game accounts (which are linked to real personal data). Going to trial just to try to prove a point wasn't worth it for me, but at least I have seen the national authority for data protection actualy reading the documents I have submitted, fundamenting their ruling with quotes from them.
