Trump's @POTUS Twitter account used Obama crowd image

Mr Trump inherited the official presidential account as he was sworn in as America's 45th president.

The original image showed flag-waving crowds in front of the US Capitol.

But it was changed about an hour later, amid claims from Mr Trump's opponents that crowds at his inauguration were not as large as in 2013.

Trump supporters on social media branded claims Mr Trump was trying to make his inauguration appear better-attended "pathetic" and a "non-story".

Trump's Twitter milestone: 20 million followers

Trump has been climbing the Twitter charts recently, thanks in part to his frequent use of the social networking site. Sometime on Monday he surpassed the 20 million mark.

According to the measuring tool TwitterCounter, Trump is the 68th-most-followed user on the site, just behind Canadian singer Avril Lavigne and right ahead of Indian actor Aamir Khan.

Trump's aides had been keeping a close eye on the follower number, waiting for the account to reach 20 million.

Extremist images 'fingerprinted' by tech firms

The four tech firms plan to create a database that contains "digital fingerprints" of the content.

The database will be used to screen uploads in order to spot violent or extremist material before it is shared.

Eventually, the database will be made available to other firms keen to police this content.

"There is no place for content that promotes terrorism on our hosted consumer services," said a spokesman for Twitter in a statement.

He said the initiative was aimed at the "most extreme and egregious" images and videos.

MPs debate porn block for Twitter

The Digital Economy Bill will lead to sites that do not ask for age verification being blocked.

It received an unopposed third reading from MPs on Monday evening, meaning it is set to become law.

But John Whittingdale, the Tory MP who first tabled the bill in July, is not convinced it will solve the problem.

But other have their doubts.


Twitter announces more tools for dealing with abuse

The "mute" button, which enables users to not see tweets from individual accounts, is being extended to prevent tweets containing chosen key words or phrases appearing in the notifications bar.

It will also enable users to opt out of seeing conversations they are added to.

There will be more categories for reporting offensive material as well.

Twitter admitted the steps would not remove abusive conduct from the platform altogether.

Twitter to cut jobs as revenue growth slows

In the three months to September, revenues rose 8% to $616m. That was better than forecast, but lower than the 20% rise in the previous quarter.

The number of average monthly active users rose 3% to 317 million.

Last month, Twitter hired bankers ahead of a possible sale, but bids from potential suitors such as Google and Salesforce failed to materialise.
