Banned from the internet

I have been thinking for long now.
What to do with these guys who send you this stupid chain letters like "yahoo is closing down" "a little girl of 4 is dieing" "lord of thirumala has send you this mail with luck as attached" etc etc.

There are hundreds of them. I tried
preaching. did not help much.
i found this today.
They say
Never send chain letters via electronic mail. Chain letters
are forbidden on the Internet. Your network privileges
will be revoked. Notify your local system administrator
if your ever receive one.

Ha ! this is enough to scare them off ! I can send them the link and say that u will be banned from internet if u ever send me a stupid chain letter again !
