Also in July, a Phoenix-based FBI agent sent a message to FBI headquarters, Alec Station, and to FBI agents in New York alerting them to "the possibility of a coordinated effort by Osama bin Laden to send students to the United States to attend civil aviation universities and colleges". The agent, Kenneth Williams, suggested the need to interview all flight school managers and identify all Arab students seeking flight training. In July, Jordan alerted the U.S. that al-Qaeda was planning an attack on the U.S.; "months later", Jordan notified the U.S. that the attack's codename was "The Big Wedding" and that it involved airplanes.
Bin Laden said he had personally directed his followers to attack the World Trade Center and the Pentagon. Another video obtained by Al Jazeera in September 2006 shows bin Laden with Ramzi bin al-Shibh, as well as two hijackers, Hamza al-Ghamdi and Wail al-Shehri, as they make preparations for the attacks. The U.S. never formally indicted bin Laden for the 9/11 attacks, but he was on the FBI's Most Wanted List for the bombings of the U.S. Embassies in Dar es Salaam, Tanzania, and Nairobi, Kenya. After a 10-year manhunt, U.S. President Barack Obama announced that bin Laden was killed by American special forces in his compound in Abbottabad, Pakistan, on May 1, 2011.
More InfoMost videos enable users to leave comments, and these have attracted attention for the negative aspects of both their form and content. In 2006, Time praised Web 2.0 for enabling "community and collaboration on a scale never seen before", and added that YouTube "harnesses the stupidity of crowds as well as its wisdom. Some of the comments on YouTube make you weep for the future of humanity just for the spelling alone, never mind the obscenity and the naked hatred". The Guardian in 2009 described users' comments on YouTube as:
More InfoOn November 6, 2013, Google implemented a comment system oriented on Google+ that required all YouTube users to use a Google+ account in order to comment on videos. The stated motivation for the change was giving creators more power to moderate and block comments, thereby addressing frequent criticisms of their quality and tone. The new system restored the ability to include URLs in comments, which had previously been removed due to problems with abuse. In response, YouTube co-founder Jawed Karim posted the question "why the fuck do I need a google+ account to comment on a video?" on his YouTube channel to express his negative opinion of the change. The official YouTube announcement received 20,097 "thumbs down" votes and generated more than 32,000 comments in two days. Writing in the Newsday blog Silicon Island, Chase Melvin noted that "Google+ is nowhere near as popular a social media network as Facebook, but it's essentially being forced upon millions of YouTube users who don't want to lose their ability to comment on videos" and "Discussion forums across the Internet are already bursting with outcry against the new comment system". In the same article Melvin goes on to say:
More InfoIn September 2019, YouTube was fined $170 million by the FTC for collecting personal information from minors under the age of 13 (in particular, viewing history) without parental consent, in order to allow channel operators to serve targeted advertising on their videos. In particular, the FTC ruled that YouTube was partly liable under COPPA, as the service's rating and curation of content as being suitable for children constituted the targeting of the website towards children. In order to comply with the settlement, YouTube was ordered to "develop, implement, and maintain a system for Channel Owners to designate whether their Content on the YouTube Service is directed to Children." YouTube also announced that it would invest $100 million over the next three years to support the creation of "thoughtful, original children's content".
