After losing her husband in a terrorist attack in Jordan, an American widow has filed a lawsuit against Twitter for helping ISIS in propagating criminal ideologies and terror worldwide.

Tamara Fields from Cape Coral, Florida filed the lawsuit in federal court in Oakland California on Wednesday. She condemned the social networking giant for allowing infliction of radicalization and help to spread the propaganda of fear.

“Without Twitter, the explosive growth of ISIS over the last few years into the most feared terrorist group in the world would not have been possible,” said Tamara in a complaint.

Fields’ husband, Lloyd Carl Fields Jr., was a victim of November 9 attacks carried out by ISIS at Jordanian police training center in Amman.

She also accused the social networking giant of violating the federal law of US Anti-Terrorism Act.

Twitter has termed the lawsuit as ‘meritless’ and expressed sympathy to the family. It denied the charges that there has been no formal or informal response to the extremists using the platform.

“While we believe the lawsuit is without merit, we are deeply saddened to hear of this family’s terrible loss,” Twitter said in a statement.

It further claimed that there was never a place for terrorism on social platforms and the company’s rules have always been clear with that.

“We have teams around the world actively investigating reports of rule violations, identifying violating conduct, partnering with organizations countering extremist content online and working with law enforcement entities when appropriate,” said Twitter in a statement.

According to the papers maintained by Field’s Lawyer, ISIS has approximately 70,000 accounts on twitter, which actively post in every 90 minutes. Every account has an average of 1000 followers.

ISIS holds accounts on other social networking sites – Instagram, Facebook and Telegram. It has been accused of luring teenagers to join extremist propaganda in the name of Islam, through videos and imagery.
