+# Introduction
+
+The "Community Blocklist" is a curated list of IP addresses identified as malicious by CrowdSec. CrowdSec proactively block the IP addresses of this blocklist, preventing malevolent IPs from reaching your systems.
+
+
+# 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`
+ - 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.
+
+# Community Blocklist
+
+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.
+
+# Community Blocklist (Premium)
+
+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)
+
+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.
