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.
