That's exactly the scariest thing about all of this. Proprietary independent sites like NextDoor collect additional layers of highly-personal information and are liable to sell-out and terms-changes etc. The only way to trust that any of these things are going to stay positive for society and not move toward more and more abuse and exploitation is to design them from the beginning to be controlled by the citizens and not by a few elites or stock-holders. And they should default to avoiding collecting unnecessary personal data.
