Holy shit! That is interesting. So then would one still be bombarded with all the info that they don't want to see from those that they haven't been able to block yet but are topic-similar to those blocked, or can you more or less effectively make your own "silo". If the second point is true, what are people upset about if they can easily "chain block" entire sub-graphs of people that they don't want to hear from? That people other than them might be exposed to it?
