stevenblack_cat: Get Category from Steven Black's Host List

In rdomains: Get the Category of Content Hosted by a Domain

Get Category from Steven Black's Host List

Description

Classifies domains based on Steven Black's unified host list which blocks ads, malware, and tracking domains. The function checks if a domain appears in the blocklist and categorizes it accordingly.

Usage

stevenblack_cat(domain = NULL, use_file = NULL)

Arguments

domain	domain names as character vector
use_file	path to a local Steven Black hosts file. If NULL, downloads from GitHub once per session and reuses it

Details

Steven Black's host list is a consolidated list from multiple sources including adaway.org, mvps.org, malwaredomainlist.com, and someonewhocares.org.

Unlike the Shallalist and DMOZ lookups, this list is actively maintained, so the returned source_last_published is the fetched file's own modification date rather than a constant. See source_vintage.

Value

data.frame with the original domain name, the category, and the date of the list that supplied it
