# Roblox Register

> The independent record of Roblox groups: measured member counts, growth history,
> ownership transfers, name history, and a register of measured users. Independent;
> not affiliated with Roblox Corporation. Counts are read directly from public
> Roblox APIs and stamped with when they were taken — never self-reported, never
> estimated.

## Reading the data

- Group pages live at /group/{numeric id}; the id is canonical and rename-proof.
- Detection dates bound when this register observed a change, never the instant it happened.
- Termination status shows OUR detection date; Roblox does not publish termination dates.
