UKRINFORM journalist Lana Samokhvalova found something strange while browsing facebook for a schedule of commemorative events dedicated to the Euromaidan Revolution– she accidently unearthed an entire network of very suspicious, self-identified “Ukrainian patriots.” She quickly realized they were Kremlin trolls who had been working systematically to destabilize the situation in Ukraine:

“There was a very distinct pattern. Every two-three days, they’d urge people to bring Molotov cocktails to these commemorative events. To overthrow this government, to throw their Molotov cocktails and march on the government. It was very a distinct and systematic call for violence.”

The story provides a number of excellent techniques for recognizing the different types of troll activity.
