Believe it or not most of the fact checking sites rose during Trump's presidency and were created and staffed by left wing ideologists to try drive away the narrative of damaging material against the left, all the main global social platforms are driving left wing ideology while suppressing conservative views hence we saw Trump erased from Twitter for a lame excuse, those platforms that did not abide to this rule were wiped of the face of the earth with wild claims like Parler simply because it allow the freedoms of speech that left wing platforms are now suppressing.
I have declassified files on everything that will make your eyes water if you knew, because some of it is against the Biden's IE Joe Biden and his Son Hunter you will get banned for posting it on YT FB or Twitter even though it is not contested but factual truth, however if you print any BS about Trump's family they will let it go viral without a blink of the eye.
PS - think of some of the worst stuff that circles the internet and you are coming close to what was on the hard drives of Hunter Biden, why is this not spreading like wildfire across the news though.. well we all know why and is yet more evidence of media bias.
