Notorious hacktivist groups Anonymous and LulzSec on Wednesday urged people to boycott PayPal for the online payment system's refusal to facilitate donations to WikiLeaks. The hacktivists set up a Twitter thread, #OpPayPal, and claim that at least 20,000 people have canceled their PayPal accounts in response to their call. PayPal denies that. "We haven't seen any changes to our normal operations, including account opening and closing, overnight," PayPal spokesperson Anna Pignataro told the E-Commerce Times.
