The blocklist: by visitor, by address, by hardware.

The blocklist: where a person's decision is recorded.

Why it outranks every measurement#

Every other reason comes from a measurement. The blocklist belongs to the operator category, the only one that can overturn what was measured, because a person decided it.

Entries are applied at both /api/v1/collect and /api/v1/verdict.

Three scopes#

ScopeBlocksWhen to use it
VisitorOne browser profileThe most precise. The default choice.
AddressOne IP addressBroader, an office NAT is many people
HardwareOne family of hardware measurementsThe broadest, and only when the two above are not enough

Blocking by hardware#

A hardware key describes a device rather than a browser profile, so it reaches someone who keeps minting fresh profiles on the same machine.

A WebGL parameter hash is a graphics card plus a driver, which is a model of laptop. Before a wide entry is written, the system counts how many people it would refuse and refuses the value outright past a limit. Nothing in 32 hex characters tells you which kind of value it is.

Hardware entries expire, 30 days by default.

Blocks belong to a workspace#

An entry belongs to the workspace that created it and applies only to that workspace's sites.

Notes#

Give every entry a note. Six months later, "blocked after 40 cards on 2026-03-11" is what separates a decision you can defend from a line nobody dares remove.
