Journalist Caroline Criado-Perez has told ITV London that although she welcomes Twitter's new move to report abusive messages, there was more that needed to be done.
The social networking site Twitter has introduced a new way to report abusive messages after several London women were victims of trolling.
The online company came under fire after journalist Caroline Criado Perez received violent and threatening 'tweets'.
Lucrezia Millarini reports:
Kim Graham, who started the Change.org petition for Twitter to do more to protect its users, has welcomed the site's move to add a "report tweet" option for users who are sent abusive messages.
I'm thrilled that Twitter has started making progress on this.
Online bullying and harassment has been too common for too long, and this is a very welcome first step toward online safety for women.
There are always improvements that can be made, but this proves that if we speak up together we can really have an impact.
Caroline Criado Perez said it was "great" that Twitter had taken a "first step" in dealing with harassment on the social media site, but said more needed to be done.
Ms Criado Perez, from north London, was one of a number of women who were subjected to a torrent of abuse by Twitter users last month.
Ms Criado Perez said: "It's great that Twitter has listened.
"There are still issues: users have to agree for the report to be potentially shared with the harasser, and there are some boxes that could be auto-populated that aren't. But overall, this is a fantastic first step."
Twitter has launched a "report tweet" feature aimed at helping people who receive abusive messages.
A number of womern were recently targeted on the site, including Walthamstow MP Stella Creasy. Over one hundred thousand people signed a petition to get the site to improve its procedures for dealing with abuse.
Life in Victorian London during Jack the Ripper's 'Autumn of Terror' is brought to life on Twitter.
Thank you for following the Whitechapel Real Time campaign. Welcome to Victorian London, 1888…
Jack the Ripper historians are pooling their knowledge into a Twitter feed which launched today.
They hope to show what Twitter might have looked like if it was around when the notorious killer stalked the streets of Whitechapel, 125 years ago.
It will include tweets from imagined detectives, reporters and local workers.
The project can be followed @WChapelRealTime
A 33-year-old man has been arrested in Bristol in connection with a stream of violent abuse directed at Walthamstow MP Stella Creasy and campaigner Caroline Criado-Perez on Twitter.
In a statement the Met Police said:
"Detectives from the MPS have this morning arrested a 33 year-old-man, on suspicion of committing an offence under the Protection of Harassment Act, 1997.
"He was arrested at an address in Bristol by officers from the MPS Police Central eCrime Unit as part of an ongoing investigation into allegations relating to threats made on Twitter. The man will be taken to a Bristol police station.
"He has been arrested in connection with allegations made to police by two women, who made reports to police on 25 and 29 July."
The case of 21 year old Emma Way from Norfolk should be a warning to any social media users who feel like boasting about their exploits.
Emma Way tweeted in May, "'Definitely knocked a cyclist off his bike earlier - I have right of way he doesn't even pay road tax! #bloody cyclists."
She appeared on ITV News Anglia to apologise, calling the outburst a 'stupid tweet' but was later charged by Norfolk Police for careless driving, failing to stop after an accident and failing to report an accident.
She also lost her job an an accountacy firm.
The twitter account in the name of Daisy Abela posted just before 10am on Saturday:
'Just had a full on barny with a cyclist he started banging on my roof so I purposely run him over'.
She ended the statement with a 4 letter expletive.
In a subsequent tweet she said she was 'definitely still drunk' and hates cyclists.
She continued, posting on the social networking site:
'I knocked him off his bike but still managed to continue my journey with 1 wing mirror lol.'
The account, which states the user is from Bromley in south London, later apologised saying her tweets had been 'blown out of proportion.'
