Have the russian trolls infiltrated DU?

I've seen a few discussions about politics go off the rail lately. Some replies devolve to hostile personal attacks. The Russians have proven themselves to be very adept at stirring the pot, getting americans to turn on each other. I always say they know how to get the most bang for the buck. Hire a few trolls and spend a couple thousand to disrupt our political system and elections. Using an array of espionage tricks they will steal our latest weapons systems, spending a few million to get billions of dollars worth of American research. Way cheaper than having to do it themselves.
