Does forwarding spam to an email administrator perpetuate the issue?

A friend received a spam email from himself in his inbox. I often wondered if malicious code could be in an email and make things worse by forwarding the email on to someone else or even an email administrator alerting them of this problem. This doesn't necesarily apply only to a Yahoo email account.

Does forwarding spam to an email administrator perpetuate the issue?
In any program---when you forward any item, you first have to open it---and that's the problem.


With Spam---just opening it triggers an alert to the spammers that they have found a valid and responsive address. They then flood you with more---AND---also sell that address to their cronies, who jump on the band wagon.
