if you've only seen the hidden wiki sites, you barely scraped the dark web.
it is called the dark web because it is not only unindexable using standard methods (so, no Google Darknet), but also because you cannot pinpoint their actual geolocations.
as such, the most dangerous places are only known to actual criminals, who are unlikely to share them on any wiki (and if they were, they'd just change the address again).
the dark web is no place for amateurs. that is why it is obscured and hard to use.
it is a lesson to learn: whether dark web, deep web, or none of the above, you should never patronize websites you do not know or trust. there are scammers everywhere, and not all deep or dark websites are scams, but if you don't know for sure, you should assume the worst. it will only save you headaches.
