Facebook has been accused of deactivating a number of pages, including those created by activists planning to have anti-cuts protests.
Among the deactivated pages are UK Uncut and pages created by students during last December’s university occupations.
It is unclear how many groups have been affected.
Administrators for the deactivated profiles say links between activists have been broken in the run up to the May Day bank holiday.
However the social networking site denied that there was any political motivation behind the move saying it deactivated the pages because they were not registered properly.
A Facebook representative said, "As you may know, Facebook profiles are intended to represent individual people only. It is a violation of Facebook’s Statement of Rights and Responsibilities to use a profile to represent a brand, business, group, or organization. As such, your account was disabled for violating these guidelines."
The company said a number accounts were suspended at the same time as relationships between groups are affected with the deactivation of pages.
The company did not reveal how many accounts had been deactivated. A spokeswoman for Facebook said the affected administrators would be sent an email and instructed about how to re-activate their accounts correctly.
The company said the process could take several days.
