Hiding abuse from the end user only stops direct forms of abuse, but it won't stop all abuse. Revenge porn is a classic example because that is usually directed at everyone in a target's life without needing to reach the target themselves. Imagine a scenario in which the target uses a client that aggressively hides content. However since this system is protocol based, other users would be using clients that aren't as aggressive. What happens if an abuser responds to every post their target makes with a revenge porn image? Maybe the victim of the abuse never sees that image because of their clients settings, but numerous people following them do. Isn't that still abuse even if the target doesn't see it? How do you stop this type of indirect abusive behavior without some centralized authority?
