The Defamation (Operators of Websites) Regulations 2013
Section 5 of the Defamation Act 2013 (“the Act”) (c.26) provides a defence for the operator of a website where a defamation action is brought in respect of a statement posted on that website if it was not the operator who posted the statement. The defence can be defeated if the claimant can show that it was not possible for them to identify the person posting the statement, the claimant gave the operator a notice of complaint in relation to that statement and the operator did not respond to the notice of complaint in accordance with these regulations.
