How does Cloudflare's IP reputation system differ from a simple IP blacklist?

Cloudflare's system is more nuanced than a simple blacklist. It uses a reputation *score* based on a variety of factors, not just a binary 'blocked' or 'allowed' status. This score considers the severity and frequency of malicious activity, allowing for more granular control and reducing false positives. Blacklists are often static lists, while Cloudflare's reputation is dynamic and constantly updated.
