"BP has been accused of hiring internet 'trolls' to purposefully attack, harass, and sometimes threaten people who have been critical of how the oil giant has handled its disaster in the Gulf of Mexico. The oil firm hired the international PR company Ogilvy & Mather to run the BP America Facebook page during the oil disaster, which released at least 4.9 million barrels of oil into the Gulf in what is to date the single largest environmental disaster in U.S. history. The page was meant to encourage interaction with BP, but when people posted comments that were critical of how BP was handling the crisis, they were often attacked, bullied, and sometimes directly threatened. ... BP's 'astroturfing' efforts and use of 'trolls' have been reported as pursuing users' personal information, then tracking and posting IP addresses of users, contacting their employers, threatening to contact family members, and using photos of critics' family members to create false Facebook profiles, and even threatening to affect the potential outcome of individual compensation claims against BP."
