In mid-January, the Buy Nothing group in Milton, Washington, interrupted its usual feed of free baby onesies and old desk chairs with an abrupt announcement. The group, wrote admin Mari Pepping, would “no longer be associated” with the Buy Nothing Project, the official name for the Facebook-born, neighborhood-specific online communities that trade gently used stuff among themselves. “Those of us who admin do it for the love of our community and our neighbors,” Pepping wrote of the volunteer members who screen posts and moderate groups, but Buy Nothing’s “core values” had changed in recent years: strict neighborhood boundaries, once a central tenet, were suddenly up for debate; the founders had even formed a public benefit corporation, tried to move operations onto a proprietary app, and trademarked their name. The post went on to claim that this newly professionalized Buy Nothing would shut down or “take over” local groups that failed to follow these new principles. Buy Nothing Milton would now be called, rather pointedly, Gifting With Integrity Milton (North). “Groups are getting shut down,” Pepping told me on a recent call about the existential crisis playing out in a once harmonious space for finding an Ikea Kallax. “I feel like they called all-out war.”
