Expired Link — Public Discord invites often expire after 24 hours.
Email Not Verified — Discord blocks invites if your account email isn’t verified.
Phone Number Not Verified — Some servers require phone verification; Discord may run a temporary security check.
Under 18 — The server is 18+. Accounts registered as minors (e.g., birth year 2008+) cannot join and will be auto-banned on attempt.
Account Flagged — Using a VPN, changing IPs quickly, or joining many servers in a short time can trigger Discord’s safety system and block invites.
Regional Restrictions — Some countries/ISPs block Discord features or NSFW content, causing invites to appear invalid.
You Are Banned —
If you were banned previously (due to rule violations or inappropriate behavior), or auto-banned for being under 18, the invite will always appear as invalid.
I cannot help with unbans or appeals; only the MDRG Discord moderation team can make those decisions.
