The dark web is just a part of the wider deep web, with the whole being inaccessible via normal search engines
Whilst the dark web has a reputation for being unsafe and mainly used for illegal activities, this is not the case.
It can be a place for safe communication for whistleblowers and those in repressive nations, and reputable organisations such as the New York Times have mirror sites that are only accessible via the dark web for this reason.
It is possible for law enforcement to access the dark web and track users, and criminals on the dark web should not assume that they won’t be traced.
The dark web can be a place for legitimate reasons, such as to avoid big companies collecting data, but care must be taken.
