I got this: "<family member> wants you to be their emergency contact on Nextdoor. In case of emergency, <family member> wants their neighbors to be able to message you via Nextdoor. Please accept their invitation to join and connect on Nextdoor so that you can be their emergency contact." This is scummy manipulation also. They now have my email address. That's an emergency contact, right there. But they aren't going to let anyone use it unless I "join". I accept that there's a case for needing my permission here. I'd be happy to give them permission to email me if a signed-up neighbour of my family member wants to send me an emergency message. But no, I have to sign up for their entire service first. I passed, and selected the "don't email me again" option. If my family member wants the neighbors to be able to contact me, then they can pass on my phone or email directly.
