• For our friends in the EU, Econsultancy has several posts to prepare you for the e-privacy directive - the grace period ends in only a few short weeks. Unfortunately, only 23% of web users would say yes to cookies when asked. And non-compliance to the directive likely will harm your business. Fortunately, the powers that be are not going to be hard-nosed about compliance right away. Says ICO's Dave Evans:

"We have a team of investigators, but we won’t necessarily be trawling the internet looking for abuse of the directive. In time, we may choose to look at particular sectors to see how they are informing users, based on the information we have received.

Enforcement won’t be driven by individual complaints though, and how we deal with this may well depend on the response from business. For example, if someone says, 'we’re not doing anything about this', then we may pay them more attention.

All of our enforcement actions are likely to be in the form of negotiations. If people listen to our advice and are prepared to take steps towards compliance there shouldn’t be a problem."
