A set of new rules on "hateful conduct and abusive behavior", implemented by Twitter at the end of previous year, added additional content, such as "hateful imagery", to the category of material banned because it constitutes "specific threats of violence or wishing for serious physical harm, death, or disease to an individual or group of people". The massacre resulted in the deaths of over 20 children and several adults.
In a tweet Tuesday, WikiLeaks called out the unanimous ban of Jones' program as a suspicious move from the Silicon Valley giants.
"Accounts like Jones' can often sensationalize issues and spread unsubstantiated rumors, so it's critical journalists document, validate, and refute such information directly so people can form their own opinions", said Dorsey.
"This is what serves the public conversation best", he added.
Senator Murphy rejected the criticism, arguing that restrictions on free speech by companies could not be compared to government censorship and that the case of Jones - who is a controversial figure standing accused of endorsing conspiracy theories and bullying - would not lead to more cases of online censorship of popular voices.
Jones' Facebook account has also been suspended for 30 days but he still has a "verified" Twitter account. "When users violate these policies repeatedly, like our policies against hate speech and harassment or our terms prohibiting circumvention of our enforcement measures, we terminate their accounts".
Jones earlier this week responded to the shutdowns of his accounts by slamming social media platform providers as "lying bullies".
"We didn't suspend Alex Jones or Infowars yesterday", he wrote.
Facebook blocked four of Jones's pages on Monday morning, followed by YouTube's decision to delete his Infowars page, which boasted 2.4 million followers.
