Discord is a common scam vector for game-hype-cycle fraud. GTA 6 attracts plenty.
Common patterns
Servers offering 'leaked builds'. Direct messages from accounts claiming to have access. Phishing-style invites that fish for account credentials. Crypto-coded 'NFT GTA 6' offers - none of these have any official basis.
How to handle
Treat unsolicited DMs as suspicious. Don't click links from untrusted servers. Don't share account credentials. Report to Discord trust-and-safety when appropriate.
