Hello, security engineer and systems researcher here. For future tournaments I advise the hosts to implement a digital identity verification system to prevent fraudulent voting. Something like a multi-factor identification process requiring two or more Strong Identifiers, such as a mobile number combined with a personal-use account (Steam, Discord). These can be used to verify the individuality of voters. Activity-based identification, such as one's Discord post history, is a very strong indicator of organic human identity. Such systems are needed to ensure the integrity of events such as this one.
