YouTube has taken down four videos posted by the whackjob conspiracy theory incubator Infowars, according to BBC News. In addition, Infowars has been hit by a penalty known as a "community strike", which stops it broadcasting live for 90 days. News about the removals came first from Infowars, which said they were deleted because they were "critical of liberalism". The videos have been posted separately to the main Infowars website.
