Don't know how generally familiar the NextDoor app is, but it's for people in a given neighborhood to let other know about garage sales, cougar/bobcat sighting, temporary needs (e.g. my daughter needing to borrow a graphing calculator), a rash of break-ins, etc.. IOW it's supposed to be for ordinary stuff-of-life, but anti-Covid-vax crazies and Covid-vax-mandater crazies just couldn't resist polluting the DU member's local group with their competing inanities. Not unlike DUpipo's annual How I'm Going to Ruin My Family's Thanksgivings and Christmases brag-ritual.
