Berlingske blocks readers who have adblockers installed.

Ah those lovely crazy Danes, the land of the forbidden deeplink, the latest windmill they're fighting now is adblockers. Danish media house Berlingske has gone so far as to block people from reading BT if they have adblockers installed - instead they are greeted with this;
--- Dear Reader message
You can read a google translation of that page here - they say;

We can see that your computer has installed an AdBlock, which allows us can not show you our ads on the website.

We can only give you free journalistic quality content, if we have ads on our sites, because they pay very much the costs associated with running a website. If ads will be removed, lost our income, and then we will not be able to continue to offer you free news on www.bt.dk

Naturally this started a thread over in AdblockPlus' forums on how to get around this.

This began with AidOnline's charity plugin - it replaces teh ads of a newspaper (or website) with their own, and when you surf you collect donations to charities involved. This didn't go down well when the newspapers realized that their advertising space was 'hijacked' and on Aidonline's homepage it now reads (bad google translation);

After a meetings with the charitable organizations where it was clear that pressure from their partners have been too large, AidOnline.com and organizations have agreed to stop cooperation immediately.
The computer program AidOnline which works by blocking advertisements on the Internet and use the space to insert new advertisements will not continue. The program worked by the user downloading a little heart into their computer.

I can understand the need to safeguard the media space that advertisers in fact pay for, but this will not wendell. I mean end well. Sorry, wendell, that's your cue.
