The Shanghai Underground makes every effort (e.g., 1024 bit encryption, firewalls, proxy servers) to keep your personal information personal. However, the East is Red; not just Red, but a deep, dark, omnivorous Red, and as such we can not guarantee that your personal information will not become Shanghaied.
Should the Shanghai Underground manage to successfully capture your personal information (such as email and IP addresses) without the perusal by outside enemy forces (e.g., Microsoft), then such personal information will rest encrypted, 'offshore', and remain strictly confidential.
Any attempts to infiltrate and sabotage the lair of the Shanghai Underground will face an onslaught of guffaws and derisions.
