Gateway shards on Kubernetes
Double Counter verifies every member who joins a server and blocks alternate accounts, ban evaders, raids and VPN abuse. It combines a proprietary device fingerprint with graph analysis over the largest identity dataset on Discord, with near-zero friction for legitimate users.
The problem
- Community moderation breaks down when banned users return under a new account minutes later.
- Each server only sees its own bans, so cross-server context never accumulates.
- Classic checks (account age, captchas) are trivially bypassed with VPNs and fresh devices.
The Tellter answer
- A one-click verification screen that fingerprints the device and browser, then matches it against a graph of 40M+ identities.
- Verdicts in seconds: allow, flag for staff, or block — with the reasoning exposed to moderators.
A member joins
Double Counter DMs a one-time verification link and locks the server until it is completed.
