What Was It?
Rawr!!! was a thread made by GPFontaine on February 17, 2009. This thread was made to exploit a flaw in the forums. In the first post, after a Hulk-like speech from GPFontaine, he posted a code which will not be posted here because it's an exploit and we don't want anyone to use it to make a Goatse thread.
What Did It Do?
This code changed the complete style of the forum. It led to a CSS page that told the forum what to do next. Each page was something different. It changed the border and colors of the page, and even put a background on some of the posts. The pages were chaotic, looking like an insane MySpace girl who went wild. GPFontaine even added music.
