 # Community Blocklist Variation and Eligibility
 
 The rules are different for free and paying users:
- - Free users that **do not** contribute get the `Community Blocklist (Lite)`
- - Free users that **do** contribute get access to the `Community Blocklist`
+ - Free users that **do not regularly** contribute get the `Community Blocklist (Lite)`
+ - Free users that **do regularly** contribute get access to the `Community Blocklist`
  - Paying users get access to the `Community Blocklist (Premium)`, even if they don't contribute
 
 Regardless of the blocklist "tier" you have access to (`Lite`, `Community`, `Premium`), each Security Engine gets a tailored blocklist based on the kind of behavior you're trying to detect.

 Free users that are actively contributing to the network (sending signal on a regular basis) have their Security Engines automatically subscribed to the *Community Blocklist*.
 
 The content of the blocklist is unique to each Security Engine, as it mirrors the behaviours they report. For example, suppose you're running the Security Engine on a web server with WordPress. In that case, you will receive IPs performing generic attacks against web servers *and* IPs engaging in wordpress-specific attacks.
 
 The *Community Blocklist* contains 15 thousand malicious IP's based on your reported scenarios.

 Paying users' Security Engine are automatically subscribed to the *Community Blocklist (Premium)*, which contains IPs that mirror their installed scenarios.
 Paying users' do not need to contribute to the network to be eligible to the blocklist.
 
 The *Community Blocklist (Premium)* blocklist content has no size limit, unlike free users.
 
-# Community Blocklist (Lite)
+## Community Blocklist (Lite)
 
 Free users that are not actively contributing to the network or that have been flagged as cheating/abusing the system will receive the *Community Blocklist (Lite)*.
 
 This Blocklist is capped at 3 thousand IPs.
+
+### Why is my Security Engine on the Lite Blocklist?
+
+Your Security Engine may be placed on the Lite Blocklist for various reasons, such as:
+
+1. Low Visibility Services
+
+Your services are self-hosted (e.g., for private video or image hosting) and primarily accessed by a small group. As a result, your Security Engine detects less malicious activity compared to public-facing services like blogs or e-commerce sites.
+
+2. Comprehensive Security Setup
+
+Your existing security measures reduce reliance on the Community Blocklist. These may include:
+- Geoblocking (restricting access to certain countries)
+- IP whitelisting with a default deny-all policy
+- VPN-only access
+- OAuth authentication (e.g., Authentik, Authelia, Keycloak)
+
+This simply a result of your security model and access requirements, its neither an issue with your setup nor a limitation on our end.
+
+3. Incomplete CrowdSec Configuration
+
+Your Security Engine may not be monitoring all your services.
+
+If you suspect this might be the case, refer to our [post-installation guide](/u/getting_started/next_steps) to ensure full coverage.
