An excellent way to avoid spam e-mail is to sign up for the site of your interest with a pseudo e-mail address and name. Basically, you create an account which you will use ONLY for signing up with a specific site or sites.

When you are certain the site is legitimate, you can change your e-mail address on the site or sites you trust. This sends all the spam at your pseudo address, which means you don’t have to sort through tons of spam in your real e-mail.

This method is especially useful for people who are busy, or enjoy web surfing. It will save a lot of headaches in the long run.
