At the height of the campaign, she received more than 2,500 racist tweets using the hashtag #filthyjewbitch in three days.
In her first public comments on the abuse, the Liverpool Wavertree MP said Twitter could tackle the problem in a number of ways.
“It could start by proactively banning racist words which aren’t allowed to printed in newspapers or broadcast on TV that could never be used in a positive way – such as kike – a derogative and antisemitic term for describing a Jew.”
The social media site has never publicly commented on Ms Berger’s case, and did not respond to the JC’s questions about how it had dealt with her abusers.
Ms Berger said she had made direct approaches to Twitter executives to suspend offensive users’ accounts. She now felt “let down” by the company.
“It took well over a week for some of the abusive content to be removed and even when it was, the approach was sporadic and very haphazard,” the Shadow Public Health Minister said.
“Twitter has made some improvements on the site and it’s important that you can report people – but when you are getting the level of abuse I was, it’s an onerous task reporting each and every person.”
