LPT: Got a spam or an email you don't recognize. DO NOT click the "Unsubscribe" links in it. It will only make the spammers aware that your email is "live" and you will just get even more such spam.

Even though most people don't click links in spam or unrecognized emails. I have seen that many people still tend to click the little "Unsubscribe" links at the bottom of such emails.

Don't do this, only click unsubscribe on emails you recognize you signed up for. Spammers have started including such unsubscribe links themselves. If you click these you'll only get more spam.
