Vlad Does Kagi employ any mechanism to delist from index or block known phishing or malware websites? There are many threats that are relatively easy to be avoided with automatic filters. For example NextDNS use many filters to block such sites, like Google Safe Browsing, IDN Homograph Attacks, or block newly registered domains. All this settings are also optional. They also have their own AI model to filter suspicious sites, and I believe something like this should be possible to create in Kagi.
Personally, security is much more important to me than privacy. And I see privacy as a subset of security. Someone who doesn't have my personal data will have a much tougher time attacking me (through hacking or scams). But it is not impossible. Search engines are our window to information on the Internet. That's why they should not only be private but also secure. Elimination of advertisements is, of course, an important step towards more security, but it is not only necessary. And right now, I see only one SE that is capable of implementing such measures, and it is Kagi.
