Agree to that, and it should be subject to serious statistical analysis. This is part of my profession.

Idenity theft, spam etc. to the Scandinavian countries are a less problem for us. There is one advantage in our language.

I still mean that that is an unscientific conclusion. And spam, fraud should be broken down on categories. You can filter out 99.9 % spam by using a "100 %" filter on a free Hotmail account. Hotmail is the best free major email service I know of. You get rid of much spam to another email account by forwarding your email to Hotmail for a while. I think Microsoft has and regularily updates a spam database related to Hotmail. Assume that you easily filter out naiive spam. What about more advanced spam and attacks? Breaking down on categories is important.
Another free, Gmail, has a relatively good filter. No need to look at the emails that ends up in the spam folder.

That was not my message. My message was that % (relative) comparisons can be misleading in lack of additional information.

On my networks, emails originating from Russia are 99.9% spam. The same is true of China and Turkey. Emails originating from the USA are less than 11% spam. These are highly telling statistics. If I get 100,000 emails from Russia and 99,900 of them are spam it is a bigger problem than getting 900,000 emails from the USA and having 99,000 of them be spam.
Spam, trojans, virii, malware, cross-site scripting, hacking, cracking and all the other security problems that exist on the web need to be dealt with in a thoughtful manner. Accepting and dealing with the data is a good start.

That is why it may be profitable to establish a customer extranet for one (sub)site.
