If you have too many passwords to keep track of then consider using a password manager program. There are a lot of them on market but be careful: some of them contain "adware" which will pop up ads every time you are online. Most of free password managers contain some degree of adware. Here's one that doesn't: http://www.roboform.com/

7. Never share your password with anyone else. If you have to, then change it immediately afterwards.

8. Avoid using "dictionary" words. There are password-cracking programs that will check every word in dictionary. If you want to use words then break them up with non-word characters. For example: BuIlT*99$APPlE is difficult for anything other than most sophisticated password-cracking program to guess because it is combined with non-alphabet characters and it is in mixed case.

9. Don't use "password" or "none" as your password! Don't even use "PaSsWoRd"!

10. If someone calls or sends you e-mail claiming that they are from your bank, or credit card company, or anywhere else that you have a password with, NEVER give them your password or PIN no matter what story they tell you. It's a scam. No one will ever ask for your password. Legitimate administrators of your password-protected accounts do not need your password to access your files during normal course of their business dealings with you.

4. Don't list your email address on your own web site in plain html or as a link to a contact form. Spammers use automated robots to capture these addresses and add them to SPAM databases. Instead use an email cloaking script whenever you need to show your email address. You can search at Google.com using phrase "email cloaking" and come up with a lot of options. Just pick one that works best for your particular needs.

5. Do not buy anything from a company that sends you SPAM. Not only might company or offer be a scam but you are jumping right into fire by letting spammers know that your email address is active and that you buy from spammers. Your address will be sold to thousands of other spammers.

6. Never reply to a spammer or click "remove my address" link. That only lets them know that your address is good.

7. If your email service or email client comes with SPAM filters use them.

8. You might want to think about subscribing to a SPAM prevention service. Search on Google.com for "SPAM prevention service" and review your options.

Following these simple tips could cut your SPAM down by as much as 90%. Wouldn't that be great!
