whatever. i hate facebook, i dont use their crap. but im not going out of my way to block their AP protocol any more than i would their SMTP protocol.
when their activity in a specific context demonstrably, negatively affects my system, ill take action as i would any negative impact from any protocol on any of my services.
when i get a spammer, i block them. but again, im not going out of my way to spite some big asshole company, and potentially lose out on coordinating an offramp for those trapped in its walls.
everyone here as proven one thing: there is no technical reason to block threads. its entirely political/moral/spite and a lot of 'maybes'.
