There's way too much random shit being thrown around about the Bidens at once. Some of this feels like false data to poison the well.
I believe the Hunter Biden pictures and videos, and the emails detailing Biden's corruption in Ukraine. I don't believe the diary leak, or the unsourced claim that it was Biden specifically who sold out the Chinese CIA assets.
(I remember the CIA story from back when it was first reported, there was never a link to any particular person. It was written off as just one of those unfortunate things that happened sometimes in the spy business. It also came within a few years of someone revealing they had no on-the-ground sources in much of the Middle East any more, making our drone strikes way less reliable.)
Things like that picture of Malia Obama's credit card getting mixed in with this are going to be used as "proof" that there's "tons of fake accusations" being circulated, and the obvious hand-wave is to let that color everything that comes out.
