Similar to Last Measure, the site's main page displayed a series of disturbing images and countless popups of disturbing images, such as Goatse, Lemon Party, Pillowfight, and many others, along with an audio clip of a man shouting, "HEY EVERYBODY, I'M LOOKING AT GAY PORNO!". Nimp.org utilized browser exploits to bypass pop-up blockers and generate multiple windows containing shocking images, which would move around the viewer's screen.
The website was also known for its ability to replicate itself when users attempted to close their browser, making it difficult to escape. However, it could be closed using Task Manager. Nimp.org also uses the script from Offiz (also known as "You Are An Idiot"), which caused the pop-ups to bounce around the screen, making it harder to close them.
Nimp.org was unique in its deceptive nature. Users could be tricked into accessing Last Measure by adding any keyword before the ".on.nimp.org" part of the URL, such as "screamer.on.nimp.org". Additionally, the site downloaded two files: "jews.wmv" and "lm.pdf". The video did not play or function in any way and the file was not an actual PDF file but instead a redirect to Last Measure.
