Anti-Sharing: HWID, Limits, IP-Based Detection

We build a working anti-sharing setup by hand: an HWID limit as the first barrier, collecting online IPs across nodes via the panel API, a threshold for sharing, and ban/reset buttons. Why HWID alone doesn't save you was covered in the theory; here we close the gap with detection based on actual connections.

We covered the mechanics in the theory piece "Detecting Key Sharing": HWID is checked only when the subscription is fetched, while a raw vless:// connects to the node bypassing it entirely. That means real detection is built on actual connections — on online IPs from the nodes. Let's go layer by layer.

Layer 1: HWID limit as the first barrier

HWID doesn't catch sharing of a raw config, but it cuts off the laziest variant — "fetched the subscription into five apps." It's set on the subscription in the panel:
