How is it made?
Considering the data model of the Tracker Radar, generating a verbatim list of hosts would not work well and cause many issues for host list based content blockers, like Blokada.
Instead, we have developed a script that generates the blocklist in a bit different way. First of all, it will generate hosts with subdomains (and not top level domains), and will not include entries for very common subdomains, like
api, that could easily break things. Second, it will only include entries for domains, for which the Tracker Radar detected enough of tracking resources for that subdomain. This, again, helps to eliminate entries that could break things. And finally, some categories, like CDN or Online Payment, are also ignored and not included in the list.
With this approach, we decided to err on the side of caution. Currently, the final list includes over 3k hosts, which seem to nicely compliment the more common blocklists.
We will adapt the script based on your feedback, so feel free to comment on this article!
