Softpedia: The most recent problems sparked last December, when AnonHQ, a common source for Anonymous-sanctioned stories, published an article named "Ten Reasons That Will Convince You That Bernie Sanders Deserves Your Vote." By Catalin Cimpanu

'Almost immediately as the Sanders article was published, almost all Anonymous small and large divisions spoke out against the idea of "Anonymous supporting Sanders." A HackRead report from December has a collection of the tweets.

'The site immediately started seeing DDoS attacks, carried out by other Anons and hacktivists. A few of the attacks lasted for a day, continued through the following months, and the most recent took place today.'
