What kind of spam does it generate? Do proposals show as notifications? Is this filterable? Only from people you follow?
Discussion
Up to clients to decide how help remove spam edits from the way they choose to notify the user.
Yes.
Im just curious how its implemented in Amethyst today and any recommendations for others based on it.
We just show every incoming edit right now. Users can block or hide the users they dont want to see or select "All Follows" in the top of the Notification bar to receive only edits from people they know and trust.
