"Correct the Record was a super PAC founded by David Brock. It supported Hillary Clinton's 2016 presidential campaign. The super PAC aimed to find and confront social media users who posted unflattering messages about Clinton and paid anonymous tipsters for unflattering scoops about Bernie Sanders and Donald Trump, including audio and video recordings and internal documents."
Thankfully, though, there are very important differences to what it looks like in China. Correct the Record has only the resources of one political party, not the entire government, and it exists in opposition to a bunch of equally well funded forces from the other party. You're free to call CTR out on their bullshit, whereas calling the CCP out on its bullshit can easily lead to prison camp or death.
In the US there are meme wars, but in China there are none -- just a boot stamping on the face of a Pepe forever.
