It appears that there are 'members' employed or affiliated by NextDoor in some manner, who police. These members are special. They have power to flag and ban over anything THEY might 'think' is a violation of ND terms. I've had this happen 2 times now, and both times had NO idea why I was being restricted! Lol,
IMO, NextDoor will kill itself with these ridiculous Kindergarten level tactics. We are adults. When you allow bored, haggard old cat ladies to administer your Social media site, ridiculous things are going to happen. This appears to be the case for NextDoor.
