Common sense is severely lacking in the real world, that's why people get completely dumbfounded by the internet, I wholeheartedly support any statements that write off people who do stupid things as stupid It's like the whole gun control thing, who the fuck leaves a loaded gun with the safety off in a bloody house with children in it? Common sense people, use it.
Yeah I just realized it's rather futile using that word with all the brainwashing going on these days, ah well, at least a few people will get it.
You have to be a complete idiot to put any information on sites such as facebook. People are being ruined daily by putting up personal information on these. Lawyers, private-detectives, etc. etc. have found this avenue to be a goldmine.
Older people simply aren't used to this kind of technology I think, that's the problem, most young people use the internet daily so they'll already know that if they post private information up there without encrypting it in any way it will be up for the whole world to see.
