I've never seen even the most censorious Americans argue that Twitter should investigate every accusation that person A is paid by group B. That scenario has actually been playing out over the past few days on American politics twitter, with a couple high profile journalists being falsely accused of taking out PPP loans, but Twitter didn't moderate those accusations and as far as I can tell nobody thinks they should have.

I don't mean this as an insult against the author, because of course Americans don't have to fear being kidnapped or tortured over it! But I don't think it's right to see this as some kind of hypocrisy.
