Snooper

Snooper is a feature Mojang is using to collect data on users, either by the client or by the server. This feature was removed in 1.13 globally because of the European Union's General Data Protection Regulations. However, it was re-added as an always on telemetry tool in Java Edition 1.18 snapshot 21w38a to "improve players' experience". It is no longer possible to disable the Snooper without client modifications.
