People are being urged to stop using social media for up to 48 hours later this week in an effort to pressure the networks into restoring control of personal data to users.
The call to strike has been issued by Dr Larry Sanger – a co-founder of the Wikipedia online encyclopaedia.
In his call to action, Dr Sanger said the strike – from 4 to 5 July – would show the “massive demand” for change.
However, some people have questioned how much impact the strike will have.
Those taking part will avoid social networks on those two days to show they have a “serious grievance” against the services.
