Stop fraudulent customers using our community blocklist. Block by email, phone, address, or payment.
Blox stops the customers who defraud you. Block repeat fraudsters, prevent chargebacks, and stop refund abusers before they place another order. Cancel high-risk orders before fulfillment. When one store flags fraud, all stores are protected. A merchant-powered blocklist that turns every block into shared protection against the internet’s worst fraudsters. Customers are deduplicated. Simple rules. No AI black box. No per-transaction fees.
- Cancel high-risk orders automatically before fulfillment without complex rules.
- Any customer blocked on another store is flagged for you to review.
- Auto-group customers with multiple accounts (e.g. different emails).
- Block serial returners and refund abusers.
- Hold customers who have issued chargebacks on other stores.

Great idea for sharing blacklist across all stores using them. Hope more people use them ASAP.
However need these improvements:
1. to allow adding of customers to the blocklist via tags.
(Update: they implemented this, working)
2. Prevent blocked customers from checking out in the first place, not cancel after they paid.
(In progress)
Unfortunately, we're still getting chargebacks due to orders being flagged high risk but were not put on hold by Blox. Thanks.
We're disappointed to see that your experience with Blox hasn't been ideal. We've reached out to resolve the issue but haven't heard back. Please let us know if we can help!
Great experience for us so far. Filled a gap we had in our current tooling, definitely a huge recommended essential item for back office, fraud prevention for anyone. Part of my personal day 1 installs here now.
