Human rights bodies have written to the Government warning of the dangers of banning people from social networks if they are deemed to be a danger.
The Government held meetings today with representatives from social media firms to talk about whether sites such as Facebook and Twitter could work in closer alignment with police.
Following the London riots, in which social media sites were used to organise criminal acts, Prime Minister David Cameron openly said the Government would look into preventing people's use of such websites if they were deemed to be organising violent or disorderly acts.
We are very concerned that new measures, made in good faith but in a heated political environment, will overextend powers in ways that would be susceptible to abuse.
"Turning off, restricting or monitoring people's communications networks are matters that require extreme care and open, detailed deliberation," the letter from a host of rights groups read.
"We are very concerned that new measures, made in good faith but in a heated political environment, will overextend powers in ways that would be susceptible to abuse, restrict legitimate, free communication and expression and undermine people's privacy. This is especially so if proposals involve unaccountable voluntary arrangements between law enforcement and communications providers."
Amongst the groups behind the letter were Amnesty UK, the Open Rights Group and Privacy International.
"It is essential that any review of regulations covering communications networks happens through a public consultation, with full details of meetings between the Government and social network platforms made public as soon as possible," the letter continued.
"This should involve a genuine multi-stakeholder process that includes not only the communications providers but groups representing broader citizens' rights such as freedom of expression and privacy."
Today, the Home Office said it held "constructive" talks with police and the social media industry. Representatives from Facebook, Twitter and RIM's BlackBerry Messenger team were invited to speak with Government.
"The Home Secretary, along with the Culture Secretary and Foreign Office Minister Jeremy Browne, has held a constructive meeting with ACPO [the Association of Chief Police Officers], the police and representatives from the social media industry," a Home Office spokesperson.
"The discussions looked at how law enforcement and the networks can build on the existing relationships and cooperation to crack down on the networks being used for criminal behaviour."
Facebook said it was happy with the discussions, noting the talks were not about "imposing new restrictions on internet services."
A statement pointed to the quality of its own reporting tools to keep people safe.
"We were pleased to highlight our array of effective reporting tools and the relationships we have built with law enforcement to keep the site safe for the 30 million people in the UK who use Facebook - especially during times of crisis," the company said.
"We were also able to revisit the positive role Facebook played during the riots from letting friends and family know they are safe to helping facilitate local clean-up operations. There is no place for illegal activity on Facebook and we take firm action against those who breach our rules."
