An Internet troll who claims to have found deep divisions among factions of the Left on Twitter laid out a plan Saturday for fellow Donald Trump supporters to exploit those fissures.

Posting on the sometimes-dubious message board 4chan, the anonymous poster wrote a post entitled, “Let’s troll Bernie and Hillary supporters systematically,” where the writer says he/she posed as a Democratic voter and trolled supporters of Bernie Sanders and Hillary Clinton in an effort to deepen divisions and help Trump secure a victory in November.

“We need to take advantage of this. This is Trump’s gift,” the 4chan troll wrote. “If we’re serious about a Trump presidency we need to start infiltrating their conversations in order to sow more divison (sic). I’m talking systematic and long-term /mischief/, not just a hew minutes trolling dumbass SJW’s. Look at the chaos and damage I was able to make yesterday, just one person, with no real rudeness in my replies. Imagine that writ large: My account is @realJohnMilIer.”

“SJW” stands for “social justice warrior.”

The Twitter account for “real John Miller” indeed seems to show activity celebrating divisions among Clinton and Sanders supporters.
