Which is NOT the bad influence from SPAM messages?

The president has signed the first ever legislation outlawing certain kinds of SPAM messages that plague computer users with unwanted junk e-mail. The new law has a long name. Officially it’s called, the Controlling the Assault of the Nonsolicited Pornography and Marketing Act of 2003. The White House says SPAM is not just annoying, but it also hurts productivity, jams up computers, and thus, is costly to the economy. The law makes it a crime, punishable by large, multi-million dollars fines for violators and possibly jail time, forbidding mass e-mails with misleading subject lines or with the sender’s identity disguised.
