+# 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 their systems.
+
+
+# Community Blocklist Variation and Eligibility
+
+The rules are different for free and paying users:
+ - Free users that **do** contribute get access to the `free blocklist`
+ - Paying users get access to the `pro blocklist`, even if they don't contribute
+ - Free users that **do not** contribute get the `degraded blocklist`
+
+Regardless of the "tier" of blocklist you have access to (`degraded`, `free`, `pro`), each Security Engine gets a tailored blocklist based on the kind of signal they share with the network.
+
+# Free Blocklist
+
+Free users that are actively contributing to the network (sending signal on a regular basis) have their Security Engines automatically subscribed to the "free 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 `free` blocklist content is capped at 15 thousand IPs at once.
+
+# Pro Blocklist
+
+Paying users' blocklist contains IPs that mirror their installed scenarios, regardless of whether they report attacks for those.
+
+The `pro` blocklist content has no size limit, unlike free users.
+
+# Degraded Blocklist
+
+Free users that are not actively contributing to the network or that have been flagged as cheating/abusing the system will receive a `degraded blocklist`. This Blocklist is capped at 3 thousand IPs.
