Above every comment box on every forum there should be a small little warning, it should read 'you are not as anonymous as you think you are'.<p>I've helped busting a few people that were distributing child pornography using my servers, and I can tell you that in each and every case they were completely surprised that they had been discovered. So secure were they in their feeling of being anonymous that their disbelief was only surpassed by the sentences they got.
