Indexes only user-submitted sites with a moderation layer on top, for a community-based approach to content curation, rather than indexing the entire internet with all of its spam, "search engine optimisation" and "click-bait" content.
So I tried searching [kotlin] and got 123 results ...
https://searchmysite.net/search/?q=kotlin
... of which the 9th result is SEO spam! It reads:
PersonalSit.es | Yes we got hot and fresh sites https://personalsit.es/ ... Shandilyahttps://msfjarvis.devTagsandroid, kotlin, rust Go to feed Go to siteradoslawkoziel.plradoslawkoziel.pl ...
That looks like junk to me. How is that possible if what the developer says is true, that it's all verified and pre-moderated?
