# How do I stop spam and fake orders with Anti-Spam?

Anti-Spam filters out spam and fraudulent orders using keyword/IP/phone blocking, order-frequency limits, CAPTCHA, and phone verification.

## Steps

1. Open **Anti-Spam** from Apps.
2. **Keyword filter protection** — add words (e.g. "test", "spam", "free") that, if found in an order, get it blocked.
3. **IP filter protection** — add specific IP addresses to block.
4. **Phone Number Blocking** — add phone numbers to block; press Enter after each one to add multiple.
5. **Minimum waiting time between COD orders** — set a number of minutes a customer must wait between COD orders.
6. **COD Order Frequency Limiter** — cap how many COD orders are allowed within a set number of hours.
7. **Captcha** — enable it so orders must come from a verified real visitor.
8. **Content Protection** — disable copy & paste on store pages and require manual entry in Express Checkout.
9. **OTP Confirmation** (requires an active Anti-Spam Premium plan) — require customers to verify their phone number by SMS or WhatsApp OTP before an order completes; this uses your **Store Coins Wallet**, so keep an eye on the low-balance warning or OTP messages will stop sending.

## Common problems

- OTP Confirmation isn't sending codes → check the **Store Coins Wallet** balance shown in OTP settings; if it's low, buy more store coins or OTP messages will not go out.
- "You don't have an active plan yet" for OTP → OTP Confirmation requires the Anti-Spam Premium plan; get the free trial or purchase the plan to enable it.
- Legitimate customers are getting blocked → review your **Keyword filter** and **IP filter** lists for entries that are too broad (e.g. a common word or a shared/ISP-level IP), and adjust the **COD Order Frequency Limiter** if genuine repeat buyers are being capped.
- Plan shows Expired → OTP Confirmation and other premium protections stop working; renew the plan from the Monthly Usage panel.
