I just came across a site called GiveSendGo who have picked up what GoFundMe tries to destroy, the protection of everyone freedom.
In a post on gab, GiveSendGo mentioned for everyone to dispute the charge with your bank, instead of using the GoFundMe refund button. This will generate a $15 fee and hopefully bankrupt them, or at a min, hurt their bottom line.
Call to action: Call your banks and dispute the donation you gave to the truckers via GoFundMe. Force it. They want to steal from people; you hit them back hard with their pocketbooks.
