I absolutely agree, except that reputation should be just as individually determined as the first two mechanisms. Reputation in the real world is utterly subjective, and that's what makes it useful. If you want something collectively determined, don't call it reputation, because reputation isn't collectively determined IRL.
Call it community response, or something, since that's what it will likely be.
I look forward to the eventuation of a distributed blockchain social media platform, that enables individuals themselves to undertake to control their content choices personally, and participate in collective choices at will.
However platforms fail to meet those goals, they subject the community to arbitrary control.
Thanks!
