Thanks. I never reply to any of these nor do I ever click "unsubscribe" if there is such an option. When you click "unsubscibe" it only confirms to the sender that your email is indeed active and you'll receive even more.
I wasnt questioning whether or not I should reply to these emails. Normally I delete them then after I always wondered if I should have reported it to the authorities. So finally today I decided to ask someone.
Thanks for the links.
You're very welcome.
