Not paying the ICO is NOT the problem
Yes: those that don't pay should be fined but the real problems are:
* web sites that pre-tick consent boxes to receive junk mail, etc
* shops/... that demand personal information that is not needed to complete the purchase, eg: a theatre recently refused to sell me tickets that I was buying in person unless I gave an address; shops that insist on an email address; ...
* organisations that share personal information when they should not
* web sites that send spam in spite of the 'want spam' check box being unticked
Little point in making a complaint about these to the ICO, they won't do anything.
