Who can show me the correct path to recover a game account that was compromised by a malicious person on the web today? I am looking for a way to provide my birth date and other secret info to prove that the account is mine. I need to get this sorted out fast so I can stop worrying about my digital footprint and items. @League_of_Legends (LoL)
