Project Goals and FAQ
The purpose and goals of this blocklist are outliined in the FAQ
The lists
For a list of domains that should not break anything, use telemetry-domains.txt.
If you want to also block domains that are not well-tested, add telemetry-domains_beta.txt to the list.
Domains that are known to break user-facing services or apps are moved to telemetry-domains_borked.txt for use at your own risk.
These lists are maintained with help from the community. Any efforts to help sort domains into the correct blocklists will help others better block non-consensual telemetry.
