On Wednesday, Facebook banned all the ads on its website and Instagram that claim widespread voting fraud, suggest U.S. election results would be invalid, or which attack any method of voting.
The company announced the new rules in a blog post, adding to earlier restrictions on premature claims of election victory.
The decision came a day after U.S. President Donald Trump used the first televised debate with Democratic challenger Joe Biden to amplify his baseless claims that the Nov. 3 presidential election will be rigged.
Citing hate speech rules, it also moved Wednesday to remove Trump campaign ads suggesting that immigrants could be a significant source of coronavirus infections.
Facebook said: “the new election ad prohibition would include those that portray voting or census participation as useless/meaningless or that delegitimize any lawful method or process of voting or voting tabulation … as illegal, inherently fraudulent or corrupt.”
Facebook also ban those ads that call an election fraudulent or corrupt because the result was unclear on election night or because ballots received afterward were still being counted.
