Fake or misleading posts have spread on social media regarding the US presidential vote, as Trump continues to dispute the outcome of the US election.
Some have been distributed by President Trump and his team, who have questioned the integrity of the election, but without providing evidence.
The BBC's fact-checking team has checked some of the main claims, which we present below.
Dead people can't vote: Michigan rumor denial
Several viral tweets on Twitter made by the team of US President Donald Trump claim that in the US state of Michigan, votes were cast using the names of people who are no longer alive.
However, Michigan authorities have responded, calling the rumors "misinformation" - and adding that votes from dead people are not accepted by the electoral system.
One of the posts mentions the case of a citizen who had the same name as his deceased father, a voter in this American state. In this case, the claim was made by trying to mix up the identities of these two people in order to present a fabricated truth, as if the vote belonged to the deceased father. However, local officials in Michigan told the fact-checking website Polifact that the son's vote was incorrectly attributed to the father in the official voting system.
The rumors have been repeated by influential accounts, including those of the president's son Don Jr - who of course also shares a name with his father - and Brexit Party leader Nigel Farage.
No evidence of computer software problems in Michigan
Posts are being widely shared online claiming an error in the vote-counting software used in Michigan, which led to thousands of ballots cast for Donald Trump being invalidated, being counted for the other candidate, Joe Biden.
The allegations have also been shared on President Trump's Twitter feed and that of Republican Senator Ted Cruz.
In fact, there was a problem in one county where votes were initially incorrectly reported for Biden, but Michigan Secretary of State Jocelyn Benson said that "the problem was quickly identified and corrected."
Benson added that the initial error was a human error, not a software error.
Other posts stated that the same error had occurred in 47 other counting centers within this American state.
However, according to Benson, "there is no evidence that this user error occurred anywhere else in the state."
Marker ballots are counted in Arizona
Several posts on social media claim that Republican ballots in the state of Arizona have been marked with a marker to make them impossible to count.
However, according to CNN, officials in Maricopa County, Arizona, have called this claim false, saying that marking with a marker does not prevent the counting of ballots.
Arizona Secretary of State Katie Hobbs confirmed on Twitter that if you vote in person "your vote will be counted, no matter what kind of pen you used."
The wrong voting map in Michigan
A Michigan voting map from election night – which shows a sudden surge of about 130,000 votes for Joe Biden, but none for Mr Trump – has gone viral on social media.
President Trump tweeted the image, which is raising speculation about voter fraud.
But, the explanation is simple – it was a data entry error that was later corrected.
Decision Desk, the election monitoring website that created the map, said: “It was a simple error from a file created by the state… the state noticed the error and produced an updated result.”
Wisconsin did not have more ballots than registered voters.
There have been false claims circulating on social media that there were more ballots cast in Wisconsin than registered voters.
One user wrote on Twitter: "Wisconsin has more votes than registered voters. Total number of registered voters: 3,129,000. Total number of votes cast: 3,239,920. This is direct evidence of fraud."
However, this figure of registered voters has been proven to be outdated, as this number increased before the US elections. The number of voters in this election, reported on November 1, was 3,684,726.
After this fact, posts with this claim were deleted, but some social media users saved it as an image, sharing it even after the denial.
