Supporters of Donald Trump have been accused of trying to trick supporters of Hillary Clinton into believing they can vote by text message.

Several pro-Trump trolls have been accused of trying to reduce the number of people turning out at polling stations to vote for the Democratic candidate by fooling them into thinking they have already voted on their phones.

Robert McNees, a t heoretical physicist, said he had spotted several fake adverts on Twitter, including at least one in Spanish, which had been posted from accounts known for posting sexist or homophobic tweets.

Some Trump supporters have been spreading these bogus adverts on social media

One ad, complete with Clinton's campaign logo, says: 'Avoid the line. Vote from home. Text Hillary to 59925.'

Several pro-Trump trolls have been sharing the ads on Twitter.

Mr McNees said he reported it to Twitter but said: 'They informed me that attempting to disenfranchise voters is not a violation of their Terms of Service.'

But a few hours later Twitter suspended one of the accounts, @TheRickyVaughn - otherwise known as Publius Gaius, a reference to a senator in the ancient Roman Empire who was known for being a fearless historian.

The adverts are extremely plausible and realistic, and have been spread on Twitter. This Twitter profile has in the last few hours been suspended

Some of the adverts are in Spanish and are clearly aimed at Hispanic voters, who are expected to heavily favor Clinton

Another Trump supporter, @Western_Triumph, tweeted last night: 'The gestapo at Twitter has suspended @TheRickyVaughn yet again! It WON'T stop the Trump Train or the Trumpenreich!'

Voting by text message or online has been recommended by some psephologists as a way to boost election turnout.
