On January 9—three days after supporters of President Trump started a riot at the US Capitol—Sean Evans decided it was time for action. Evans had seen a post on Nextdoor about neighbors running into hostile Trump supporters the night of the riot, leading to a verbal altercation that had left residents of his corner of Northwest DC on edge. Now, rumors flew online that the upcoming inauguration of president-elect Joe Biden would bring more protesters and more armed violence to the streets of his city. “I don’t want them in my neighborhood,” Evans thought to himself. In fact, he didn't want insurrectionists in the city at all.

So on Nextdoor, Evans asked his neighbors to stop renting out their properties via Airbnband VRBO. A few hours later, another neighbor devised a hashtag: #DontRentDC.
