For me the worst is NextDoor. I don’t have the app installed, but they also have email notifications. There are seemingly 100 options and I turned them all off when I first made the account. Periodically they add new ones and auto-enable them for everyone. There is not universal way to shut them off, short of blocking them all together or deleting my account. The account was such a pain to setup that I’m hesitant to delete it, for the 1 time every couple years where it’s useful.
I flagged them as spam the other day.
Even worse with ND e-mails are how they've absolutely perfected the cut-off character limit for what's being posted in your area. So my inbox is just perma-barraged with click-bait-y "This place on Smith Street has the best...", "Health officials are investigating an outbreak of...", etc.
Yep, I straight up deleted my Nextdoor. Nextdoor itself is spammy and ad ridden. And most of the content in the community is also just spam anyway.
My neighborhood has a WhatsApp. I engage with it if I feel like it. Works great
