How to block bot orders and reduce fraud on your online store

Key takeaways

• Fraud orders cost more than their value: chargeback fees, lost goods, locked stock and staff time.
• The warning signs are bursts of orders, mismatched countries, data-centre or VPN traffic and repeat details.
• Layer your protection: block countries you do not ship to, block VPNs and bots, and block known bad IPs, emails and phone numbers.
• Blocky Fraud Filter IP Blocker does all of this on Shopify, Wix and Ecwid without editing your theme.

What bot and fraud orders look like

Most stores notice fraud the same way: a sudden run of orders that look slightly wrong. Common patterns include:

• Bursts of orders minutes apart, often for the same product or the cheapest item in the store.
• Card testing: many small orders with different cards, used to check which stolen cards still work.
• Billing and shipping countries that do not match, or a shipping country you rarely sell to.
• Traffic from VPNs, proxies or data centres rather than home or mobile networks.
• Repeat details: the same email pattern, phone number or IP address behind several "different" customers.
• Fake sign-ups and abandoned carts that hold stock but never convert.

Why fraud costs more than the order

When a fraudulent order goes through, the card owner eventually disputes it. You lose the money and the goods, and you usually pay a chargeback fee on top. Payment providers also watch your dispute rate. A store with too many chargebacks can face extra fees, reserves or an account review.

There are hidden costs too. Bot orders reserve stock real customers could have bought, skew your analytics and ad data, and take up hours of staff time in cancellations and refunds.

Five layers of protection

No single setting stops every fraudster. The stores with the fewest problems combine several simple layers:

1. Block the countries you do not ship to. If you only sell in the UK and EU, there is no reason to accept orders from elsewhere.
2. Block VPNs, proxies and bots when you see repeat attacks. Real shoppers rarely need to hide their location to buy from you.
3. Block known bad details. After a fraud order, add the IP address, email and phone number to a blocklist so the same person cannot return.
4. Review risky orders before you ship. Use your platform's own fraud analysis and hold orders that look suspicious.
5. Make your terms clear at checkout. A required terms checkbox gives you evidence when a dispute does happen. See our guide to adding a terms and conditions checkbox.

How Blocky protects your store

Blocky Fraud Filter IP Blocker blocks bots, VPNs and fraudsters before they reach your products or checkout. You can block by country, IP address, email and phone number, and it runs on Shopify, Wix and Ecwid.

Set it up in five steps

1. Install Blocky from your platform's app marketplace.
2. Choose the countries you want to block or allow.
3. Turn on bot and VPN protection if you have seen automated orders.
4. Add the IPs, emails and phone numbers from past fraud orders.
5. Test the store from another network to check real shoppers get through.

Merchants often see results fast. One lighting store told us: "We were having issues with bots placing hundreds of orders every day. Their devs got on it, and we haven't had a bot order since."

Card testing: the attack most stores miss

Card testing is one of the most common attacks on small stores. Fraudsters buy lists of stolen card numbers and use cheap products to check which cards still work. The orders are usually tiny, placed seconds apart, and come from many different names and addresses.

Even when the payment is declined, each attempt can cost you a processing fee, and the successful ones turn into chargebacks later. If you see dozens of low-value orders or failed payments in a short time, treat it as an attack: turn on bot and VPN blocking straight away, and block the IP ranges and email patterns involved.

Where fraud protection goes wrong

• Refunding and moving on. If you only refund a fraud order, the same person can try again tomorrow. Always block their details.
• Blocking too broadly. Blocking whole regions you actually sell to costs you real customers. Start with countries you do not ship to.
• Shipping before reviewing. Once a parcel has left, it is very hard to recover. Hold high-risk orders until you have checked them.
• Ignoring the small orders. Card testing often starts with low-value orders that look harmless.
• Setting and forgetting. Fraud patterns change. Review your blocklists and blocked traffic every month.

A quick fraud checklist

• Block countries you do not ship to.
• Turn on VPN and bot blocking during attacks.
• Blocklist the IP, email and phone from every confirmed fraud order.
• Hold high-risk orders for manual review.
• Add a required terms checkbox at checkout.
• Check your dispute rate every month.
