The statement replaces that published by Oftel, the regulator's predecessor, in August last year.
As required under the Communications Act 2003, the statement clarifies when and how Ofcom can take action against those who persistently misuse networks or services to cause another person "unnecessarily to suffer annoyance, inconvenience or anxiety", but do not actually commit a criminal offence.
It is essentially a consumer protection measure to deal with nuisance behaviour, and is unlikely to be used where an alternative legal remedy is available – for example, in dealing with spammers or hackers.
According to the statement, Ofcom will act where there has been:
Where there has been persistent misuse, Ofcom will issue a notification to the person it believes responsible. This can then be followed by an enforcement notice and/or a penalty of up to £5,000.
