YouTube tweeted: "Like everyone else, we are concerned about the video we were sharing last week, and suicide is not a joke and should not be a motivation for getting traffic."
The company said: "We expect more video creators to build a community on @YouTube," and they apologize for the delay in making public comments on the video.
In the video, Paul and his friends were shocked and joked after finding the remains of suicide victims during a tour of the Aokigahara Forest at the foot of Mount Fuji in Japan. This video was released in late December with more than 1 million clicks. But Paul, 22, deleted the video from YouTube three days later.
YouTube said Paul's account was flagged as violating the company's violent or image content policy after the video was deleted. Account will remain suspended for three months. Paul apologized to Twitter last week and said he did not post the video because of traffic.
He did not notice the video's attention or opinion.
