Hoaxes and chain letters
Talking about warnings, ever received a mail like this?
Subject: 'Warning: recent research has shown you get cancer from cellphones'
Content: blablabla story which seems real blablabla send this to everyone you know!!!
or something like this:
Subject: 'IBM gives away free laptops'
Content: 'blablabla so send this message to at least ten friends, IBM will see you sent them the message and you'll be eligable for a free laptop'
This is all fake, including messages containing warnings about viruses (unless you can verify them). These are all chain letters and, together with spam, take up about 70-90% of all mailtraffic! Break the chain, don't send them to anyone, delete them. The people sending these mails will try to make you feel guilty for not passing the mail on. There are chain letters known to contain 'sad' stories about people dying and getting one cent for every person the mail is sent to. When receiving such a mail allways try to verify the story. When you can't break the chain.
