I am pretty sure my friend said that his clients had been contacted....but I could be wrong.
Thinking about it, he would give the client's contact details to receive updates about the service, so that's whom Ryanair would contact, I would have thought.
But I don't know for sure, and he's out!
PS Surely, if so many people are accessing your information that your website is suffering, the solution is to improve the website, not kick off a lot of your customers. To most of us, a screenscraper is a marketing tool that some else pays for.
