Nextdoor, a ZIP code-curated and vetted social network, does not allow discussions about U.S. politics — even during an election year.

“We actually don’t allow national politics discussion at all because we find that can so quickly go off the reservation where people aren’t being kind. We try to really embrace local politics,” Nextdoor CEO Sarah Friar told Yahoo Finance’s “The Ticker” in an exclusive interview.

Unlike Facebook (FB), which allows advertisers to micro-target users and keeps political ads on the platform without fact-checking them, Nextdoor has taken a stringent policy on politics, which sounds like a rule that a family may set ahead of a tempestuous Thanksgiving meal. Friar’s approach resembles that of Jack Dorsey, her former boss at Square. Dorsey, who also runs Twitter (TWTR), banned all political ads from the site.

“In the case of ads, we just feel in the end we don’t want to be policing what’s real, what’s perhaps disinformation or misinformation. In terms of ads on the platform, which is how we monetize, we really try to make sure those ads have high utility and are really endemic to what’s local. So think about brands like Home Depot, for example, or a local grocery chain, that’s trying to pull people from online into their store, that’s actually more where we’d rather go with the platform rather than getting caught up in some sort of maelstrom on political ads — what’s real and what’s fake,” she explained.

Kill bad behavior with...kindness?

Friar acknowledged that her social media peers tend to incentivize hot takes and bombastic comments.

“These are global macro themes. They’re true here in the U.S., particularly as we think about an election coming up where people tend to move toward their tribes and further and further away from each other. But it’s also happening globally — look at Brexit. So when you’re in that moment where you’re about to make a post, maybe with some anger behind it or a rush to respond, which social media often wants you to do, we actually slow you down,” she explained.

Citing collaboration with academics like Stanford’s Professor Jennifer Eberhardt, who wrote a book called “Biased,” which is all about how to slow people down, and physician Kelli Harding, whose “Rabbit Effect” shows how “active social circles can increase a person’s survival,” Friar said she wants to stay far away from contributing to the vitriol and echo chambers that permeate the internet.

The partnership with Harding resulted in a product feature called a “kindness reminder,” which pops up if a member replies to a neighbor’s post with a potentially offensive or hurtful comment. The member is given the opportunity to reconsider and edit their reply, or ultimately refrain from posting.
