Pnrtscr.com

Pnrtscr.com is a screamer website that pretends to be a shortlink to a particular website. It is a typosquatting website that lures users into believing this is the actual prntscr.com website, a screenshot hosting website, and URLs to screenshots have 6 digits. Users would led into a screamer if they add any digits after "pnrtscr.com/". When entering, the website would contain a cookie banner, so it needs the user to accept the cookies to offer the "most relevant information." If the user accepts, the website will take the browser into full-screen mode with the flashing image of Jeff the Killer (as used in Anne.jpg), accompanied by an extremely loud, metal-like sound. This also happened if the player didn't accept the cookies.

The creator of the website was Matthew Rowland. He admitted on Reddit that he made the site as an attempt "to create a modern jump scare." The rest of the post includes information about how he created the script for the website.
