LEGAL counsel Martin Bennett has a short message for those who allow themselves to attack reputations over the internet, imagining they are safe under the cloak of anonymity. ''You can be hunted down and found,'' he said yesterday.

Mr Bennett has done just that for a Perth client, winning $30,000 in damages and costs, an apology, and undertakings from a Colac man that he won't post any more defamatory comments.

The hunt for the man's true identity proved the stuff of private detective novels updated into the age of blogs.

It is, Mr Bennett said, one of a very few such actions in Australia against the author of anonymous postings on an internet forum. He predicts it is the tip of a legal iceberg.

''There has been an increasing proliferation of internet chat sites where people feel free to hide their identities and make defamatory comments about companies and their executives and directors,'' he said in a statement released after the case in the Supreme Court of Western Australia was resolved.
