This reminds of the "WOT, Web of Trust" (haha) privacy issue in 2016: Reporters (disguising as business men) were offered data that includes the surfing habits of three million German citizens. This data was, at least partly, collected by the “Web of trust” (WOT) browser extensions. The reporters were able to use this data to identify the browsing habits of individual persons – including high-ranking German and EU politicians.
Indeed. I never trusted it. I never trust any feature or add-on that uploads anything. That includes malicious site detectors. I only use stuff that relies on local databases.
Any recommendations on malicious site alternatives?
I'm still looking to update my router (Turris Omnia) to use DNSMasq rather than Knot Resolver, which may offer an edge on DNSSec capabilities (though I believe this has lapsed), but is far less capable of being locally customised along the lines of DNSMasq.
