All hosts added and sorted. I’ll try to change the script to include those whitelists in the process, thanks for the idea. ---

I have now added a simple whitelist generator script that fetches the lists you guys mentioned. So now our ddg list shrank from 24.6k hosts to 22.4k hosts, so I think we removed a lot of false positives 🙂 ---

@Karol, this is a good source to run through our allowlisting script regularly, to help cut down on the false positives: [1Hosts/exclude\_for\_all.txt at master · badmojr/1Hosts · GitHub](https://github.com/badmojr/1Hosts/blob/master/submit_here/exclude_for_all.txt). Another one: [src/exclude.txt · master · malware-filter / urlhaus-filter · GitLab](https://gitlab.com/malware-filter/urlhaus-filter/-/blob/master/src/exclude.txt) Also consider something like step 2 here: [faq · Wiki · malware-filter / malware-filter · GitLab](https://gitlab.com/malware-filter/malware-filter/-/wikis/faq). But I would want to make sure it doesn’t exclude trackers. ---

I downloaded the latest list from [https://blokada.org/blocklists/ddgtrackerradar/standard/hosts.txt](https://blokada.org/blocklists/ddgtrackerradar/standard/hosts.txt) and sorted it and then removed duplicates. The list reduced from 23,000+ to 13,000. That means your host list has over 10,000 duplicates wasting both yours and client connections bandwidth, as well as CPU for programs that process it and need to check for duplicates. You may want to sort and “unique” the lines so as to save everyone including yourselves bandwidth and CPU time. ---

All hosts posted until here have been whitelisted. Also I added the false positive whitelists mentioned by @yokoffing, and added the sorting+dedupe step mentioned by @CleanupTheInternet . Thanks! ---

This alone will remove ~500 lines, almost all likely false positives.
