Raven and Vampire, reading your comments makes me feel wonderfully relieved that I live in Scandinavia, and not in the US of A.
It sounds as if you consider this kind of mobbing attitude, agression or what should I call it, natural and widely acceptable. I mean, do you really have that kind of lynching atmosphere thereabouts? How can you bear it, without doing anything to milden the social attitudes?
I keep my wifi open and I seriously think that it would be extraordinary bad luck, if there was a cp-d/l'r on my connection amongst the few visitors I get. Even more exceptionally bad luck would be if the impropable person would get caught while using my line for the illegal purpose. I don't use the wifi for other than occasional surfing on the sofa, checking the latest news or such. Business connections are from separate linux boxes on a different subnet so I am not immensely worried about tresspassers through wifi.
The natural solution will be public free wifi, we are just the silent supporters of this development.
