Presence detection, without compromising privacy

Using ASNs and nftables to block connections

Blocking Facebook, and similarly-toxic sites/services, is a common theme amongst those who value privacy. Facebook goes to great lengths to track everyone, regardless of whether or not they have an account or use anything they "generously" offer to the public. Previously I had a long, long list of domains that Facebook owned, and set up unbound (the DNS resolver I run) to deny lookups to those domains. This was a classic game of cat & mouse, as Facebook would frequently acquire new domains and it was basically impossible to keep up.
