New Job boards - are they a front for massive ID theft?

This post started out as a flippant remark made to someone yesterday, but it made me think further.
There seems to have been another influx of new job boards coming into the already crowded space recently. My question is simple and worrying at the same time. What would stop a foreign owner (doesn't have to be foreign of course) setting up a job board? Then building up a database of CV's quickly, with some fancy promises, only to disappear to 'farm' all the personal information they have collected and commit massive ID theft?

As far as I am aware there is nothing to stop them doing just this. All they have to do is set up a company, fill in the Data Protection Act form (which they will obviously abuse), build an appealing website and off they go!!

Slightly worrying thought isn't it?
