Simply enter the username of the subject you want to search across the websites. Toggle the "NSFW Results" checkbox if you want to include NSFW websites in the search. Then, click the "Search" button to start the search. Wait for the search to finish or start browsing the results instantly. Clicking on the sites will open a new page with the subjects' profile.
Sherlock the OSINT tool scourges the web to find profiles that match the subjects' username. Each website has a way of checking whether a profile with a username exists. Sherlock automates this process to allow users to acquire information about a subject. Sherlock On Web is a tool that provides a modern interface for the Sherlock Project.
If your local laws prohibit you from accessing NSFW websites, using Sherlock might cause legal problems. Using Sherlock sends requests to these websites as if you were trying to access them. The "NSFW Results" checkbox is unchecked by default.
