# Why Country Restriction isn't 100% accurate?

We use various data sources to identify and block unwanted traffic, including VPNs, proxies, and users from specific locations. While these tools improve accuracy, reaching 100% is impossible due to several factors:

1. **Imperfect Geolocation**  
* IP addresses can only approximate a user’s location. Some regions are mapped accurately, while others may be less precise.

2. **VPNs, Proxies, and Anonymizers**  
* Many users hide their true location using VPNs, proxies, or Tor. Some services are flagged, but new or private endpoints may bypass detection.

3. **Shared and Dynamic IPs**  
* Some IPs are shared among multiple users or reassigned dynamically, so blocking them may inadvertently affect legitimate traffic.

4. **Constantly Changing Internet**  
* IP assignments and anonymization services are continuously updated, making it impossible for any system to block all undesired traffic in real time.

**Bottom line:**  
Blocking based on IP and location is effective as a first layer of protection, but it cannot guarantee that every unwanted visitor will be stopped. For stronger security, it works best alongside behavioral monitoring and other protective measures.
