GoFundMe deplatformed Matt Braynard when he tried to raise money for the voter fraud research. He didn't even assert that the fraud happened or not and they still kicked him off for what they've said is "disinformation".
Historically in the US there have been only a handful of cases where voter fraud overturned an election, and it was in small elections with very narrow margins. Extraordinary claims require extraordinary evidence, the likes of which will not happen in a GoFundMe. The effort was meant to sow distrust and repeat the weaponized cynicism.
That's cool, but he started the campaign on November 6 and they kicked him out the next day. He didn't say anywhere that the fraud happened or not. He was just raising money for the research.
Will they let people raise money to see if theft of a bank is feasible, or to design business models for heroin dealers? They're not robbing banks or selling heroin... Where does your argument even end? It doesn't matter because it is a private platform, and if they smell BS they are free to get rid of it.
He was part of the Trump campaign in 2016 and from the 3rd to the 6th he interacted with various Twitter accounts that fueled the conspiracy and his fundraising was clearly attracting an audience who read between the lines.
GoFundMe is in their right to believe there was dog-whistling.
Bring the evidence to the court? It's funny how the side claiming there was fraud apparently has trucks full of evidence and affidavits on news channels and social media, but when it comes to an actual courtroom, where lying has real consequences, suddenly, they don't claim "fraud" anymore and they don't have any real evidence.
