Facebook sees about 5 billion items posted daily. The typical person likely sees between 10--100 items, and closer the lower end than you might think.
At a ratio of 10 : 5 billion, the non-bullshit fraction is about 0.00000002%. Or 99.99999998% of everything is bullshit in terms of relevance.
(This also means that any rating or selection system itself is operating very nearly randomly.)
If 10 items seems to few, remember that the average person uses social media for about an hour pervday --- interaction per item is 60 minutes/n, where n is the number of items viewed or interacted.
Even skilled content moderators have an upper bound in practice of about 700--800 items/day, sustained.
