But South Lanarkshire Council said all blogging and social networking sites are treated the same and can be unlocked on request.
Mark Irvine took the local authority to the UK Supreme Court to win a Freedom of Information case which has brought the council back to the negotiating table over the issue of equal pay for women. He discovered that the website of his campaign, Action 4 Equality Scotland, was blocked for access by all users of South Lanarkshire Council computers, whether staff or users of local libraries. Mr Irvine wrote to the council claiming: "I am sure you will understand my concern that the A4ES blog site appears to have been singled out for such treatment which looks, to me, very much like heavy-handed censorship."
But a South Lanarkshire Council spokesman said: "The default position of our computer systems is that all blogs are blocked.
"If a user made a request for a particular blog or social media site to be unblocked that would be considered."
