tl;dr Version

HWLink is a VM scanner and ban evader detector that uses hardware IDs to ban shitters.  IDs are only stored when the person connecting is banned.  A browser plugin is the only way this can work.  Pomf and SoS have access to the sourcecode and I have worked with them to implement this.

Long Version

HWLink is a new browser plugin I developed in concert with TGstation and /vg/station administrative staff.  BYOND – the platform on which Space Station 13 has operated on since 2006 – has many advantages, but is aging.  While I’m working on a replacement, one of the biggest problems with BYOND has become readily apparent to most server owners:  The lack of a reliable banning system.  Users wishing to bypass a ban only have to spin up one of several popular virtual machines, and can rejoin the server with a new account without issue.

HWLink proposes a simple fix:  Instead of just the hashed computer ID that BYOND sends to its users, HWLink will instead profile as many components on the user’s computer as possible, and use the globally-unique identifiers (although not necessarily proper GUIDs) of each of those components to detect ban evaders.  In addition, HWLink can detect most VMs, and can also detect randomly-generated identifiers.  Only a single matching hardware component ban can trigger an administrative alert.

While HWLink is an improvement upon the older CID-based “sticky ban” system, it’s not perfect:  Evaders can still bypass bans if they are determined enough.  What HWLink does instead is substantially increase the amount of time it takes for a given evader to bypass a ban, which serves as a harsh deterrent to would-be griefers and other troublesome individuals.

HWLink is a proprietary project, and works on Firefox, Chrome, and Internet Explorer as a browser plugin, and does not use a centralized server for data storage.  Data retention policies are up to the server owner, but commonly are only the hashed identifiers of banned or flagged individuals.
