According to his own website, he founded 4chan when he was just 15 years old.
The community website, 4chan, is famous for spawning memes such as Rick-rolling where online users are redirected to a video of Rick Astley's hit song 'Never Gonna Give you Up' .
The 4chan website claims to have 22 million users a day.
However the site has also been criticized for hosting pornographic imagery and in 2014 was used by hackers leaking naked pictures of high profile women, including actress Jennifer Lawrence.
In January 2015, Poole retired from running 4chan and subsequently sold the site to Japanese social media expert, Hiroyuki Nishimura, for an undisclosed fee.
