AltWarden
AltWarden checks new Discord members for alt accounts, ban evasion, VPNs and raids. If its database were stolen tomorrow, the thief would find no IP addresses, no emails, no Discord tokens and no fingerprints.
This copy runs only on its owner's servers, and nobody else can add it. AltWarden is open source, so you can run your own.
In October 2026 the verification bot Double Counter said an attacker may have reached records on about 28 million Discord accounts, including about 27 million IP addresses. Have I Been Pwned lists about 275,000 email addresses from the leak. Verification bots collect that data because they need it for a moment. AltWarden uses it for that moment and keeps a keyed hash instead, under a separate key for every server.
Addresses, cookies and fingerprints become keyed hashes before they touch the disk. Emails are never stored. Discord tokens are revoked seconds after sign-in. Discord IDs and names are kept, so staff can see who verified.
The verification page loads no scripts, fonts, ads or trackers from any other site. The one outside request is the server's icon, from Discord. Ordinary ad blockers can stay on.
Set a rule to Watch and it records a match and lets the member in. By default a rule stops people, and no preset is built on Watch, so this is a choice you make one rule at a time.
Any one match on the connection, browser cookie or fingerprint makes a second account an alt, and the action you choose applies.
A spike in joins tightens the rules by itself and alerts staff, then relaxes when it's over.
Anyone can see what's held about them and delete it, with no ticket and no waiting. The privacy page lists what stays.
