Although e-mail is a wonderful way to communicate, it is very dangerous because it is going to alter relationships. I want a real, colorful postcard, written with your thick black pen and your signature even if it takes 8 days to receive it.
Some people have nothing better to do than send unwanted, trashy e-mail to other people.
If you work in front of a computer, you are aware of how many trashy e-mails you can receive in a day. Some people who have nothing else to do fill their empty days sending dirty images and disgusting scenes to other people by e-mail. I think that these trashy e-mails should have some kind of regulation, but not in the same way as the other media. There should be some kind of filter of what you can or cannot receive. This trashy e-mail could even bring a serious virus to your computer.
