Know Who You're
Letting In
The DBBL Protocol is a shared reputation network for online platforms. Submit confirmed violations, query risk scores, and collectively protect your communities from repeat bad actors.
Bad Actors Don't Stay Banned
Your moderation team bans a user for harassment. They create a new account on your platform next week — or sign up for a competitor tomorrow. Every platform fights this battle alone, rebuilding context that already exists elsewhere.
The DBBL Protocol changes that. Platforms that submit confirmed violations collectively build a shared risk signal — weighted, time-decayed, and privacy-preserving — that any member platform can query before granting access.
Three Steps to Shared Safety
Submit Violations
When your platform confirms a bad actor, submit their hashed identity signals — phone, email, or username — along with the violation category and severity. Raw PII never leaves your system.
Score Is Calculated
The Protocol weighs each report by severity, recency, and your platform's trust score. Time decay ensures stale reports carry less weight. Diminishing returns prevent any single platform from dominating the score.
Query Before Admitting
Before a user accesses your platform, query the Protocol with their hashed signals. Receive a risk score, dimensional breakdown by violation type, and a confidence level. Your platform decides how to act.
Built for Platforms That Take Safety Seriously
Dating & Social Apps
A user who sent unsolicited explicit content on one platform has a high score in that category. Surface this before the first incident on yours — not after a user files a report.
Gig & Marketplace Platforms
Sellers removed for fraud or harassment don't get a clean slate when they register on a competing platform. Shared reputation closes the revolving door.
Gaming Communities
Known griefers, cheaters, and account sellers leave a trail across platforms. The DBBL Protocol aggregates that trail into a queryable signal before you invest in a new account.
Creator & Community Platforms
Protect your moderators and community members from known harassers before they cause harm. Confidential dimensional scores let you act without broadcasting details.
Five Levels of Clarity
Every score maps to a named rating so your platform can act without needing to tune thresholds.
We Never Need to Know Who Someone Is
Identity signals are hashed by your platform before transmission. The DBBL Protocol stores cryptographic fingerprints — not names, email addresses, or phone numbers. A person's real identity is never derivable from DBBL data alone.
Phone numbers are normalized to E.164 format before hashing. Email addresses are normalized to prevent alias evasion. Usernames are the only plaintext signal stored, and only because fuzzy matching requires it — they're never tied to real identity without a corroborating hash signal.

The DBBL Protocol is currently in limited access. We're onboarding platforms with active moderation programs that are willing to contribute confirmed violations as well as query scores. Mutual contribution is what makes the network valuable.
