What policies should prevent companies sending spam in the UK?

I guess I am fortunate that my BSc Computer Science degree included a module on Computing in Society. I was able to watch the Data Protection Act 1998 come into force (replacing the 1984 act). then in 2003 we received the the Privacy and Electronic Communications Regulations thanks to the EC!

Both of these laws prevent companies adding our personal information to marketing databases without our express consent and knowledge. There cannot be a default "opt-in" too. The Information Commissioner (formally the Data Protection Commissioner) deals with any requests for assessments when an individual needs to involve his office because the Data Controller in an organisation is not resolving an issue. Companies also need to register their use of our personal data, and provide a way to unsubscribe at the bottom of each marketing email etc.

Also register with the MPS to take away another excuse for companies sending direct marketing!

If any company breaks the rules, take them to task and get them to delete your personal details, ask for compensation if it's wasted some of your time too!
