Roger Waters, the co-founder and former vocalist of Pink Floyd, has taken Twitter to criticize nothing but Twitter itself as he undertook the role of being the voice for the censored student organization, the International Youth Students for Social Equality.

The British legend Roger Waters, who is known for his strong stance against all kinds of social and political injustices all around the world, has most recently pointed out a significant issue by duck-taping himself to shame Twitter.

Soon after Waters brought the tragic death of a little refugee girl, Mawda, to light on the platform, he has appeared to support the fight of the International Youth and Students for Social Equality (IYSSE), an organization which has been banned by Twitter.

Waters remarked on the fact that it is critical that people are informed of this effort to censor them as he called out to the co-founder and CEO of Twitter, Jack Dorsey, asking him what is he afraid of so much to take the freedom of speech of a socialist organization.

Under the act of online political censorship aimed at silencing left-wing and socialist views, Twitter has suspended the account of the International Youth and Students for Social Equality in the US.

At 6 am on Wednesday, members of the IYSSE noted that their Twitter account had been stripped of its profile and header image and the account timeline of tweets had been replaced by a message that says, ‘account suspended.’

The International Youth Students for Social Equality is the student organization of the Socialist Equality Party and the International Committee of the Fourth International, an international Trotskyist organization.

Launched in 2006, the IYSSE aims to build an international socialist movement of students and workers opposing militarist violence, social inequality, and attacks on democratic rights.

Here’s what Roger Waters said in his latest tweet:

Twitter has banned the International Youth and Students for Social Equality [IYSSE].

It is critical that people are informed of this effort to censor them. What are you afraid of Jack Dorsey?”
