Charity bosses have launched an investigation the North West Air Ambulance's charity's website was hit by Internet spammers - via the sites guestbook system. Online gambling and non-prescription drugs links have been dumped on the page.

The charity said it did not have the resources to monitor its site 24-hours a day. But what company does, let alone a charity?

Guestbooks are rarely monitored by site owners which therefore allows people to post all sorts of spam links to their sites.

Best way to remove the problem is to remove the guestbook.
