While social media sites and Nextdoor have been used to highlight ICE activity across the U.S. in recent days, Neighbors has been especially popular, with dozens of posts. It allows anyone to post on safety issues in their locale and users can choose to include footage from their Ring doorbell cameras where relevant. 

Forbes spoke to multiple Ring owners who’d shared warnings about ICE with their neighbors. One named Nic said it’s been helpful to know what parts of Los Angeles to avoid, saying she’d seen users posting reminders of people’s rights and not to open their doors to ICE agents without warrants. “I feel like in a time when things are so unfamiliar and scary, small peeks of hope are helpful,” she told Forbes.

The posts reviewed by Forbes feature photos and videos of ICE agents, including their locations and, in numerous cases, their vehicle type. Some posts had information on ICE agents near stores like Dollar Tree, McDonald’s, Starbucks and Target. Two alerted communities to ICE operations near elementary schools. 

Still, there are good reasons to be careful when posting on Neighbors or Nextdoor. While Ring did remove a feature where police could request doorbell camera footage through the Neighbors app last year, police can obtain information on users with a court order. Search warrants and subpoenas could be used to demand data from any business with information on those protesting ICE’s actions.
