You cannot avoid spammers, at least once or twice you are going to get spam mail. When you create a new email ID, you are not spammed at all but once you start using that email ID, you also start getting spam mails. So how these spammers come to know about you email ID? There are many places on internet from where these spammers gather emails but I am writing only those which are popular.

- You join a website whose administrator is an evil person and sell user email ID with his/her private information as well.

- You join a website whose administrator is non techcy and webmaster leaks email to his spammers friends.

- You post your email ID in forums and other portals where this email id is crawled by special software’s used by spammers to collect emails from web pages.

- Your email id is in contact list of your friend (which is obvious) and your friend’s computer is infected with spyware. All his contact emails are stolen with some private information as well and then personalized spam mails are sent. A real example I would like to give here, I met my old friend on social networking site and she was in Russia. Now she added me in her contact list and her laptop was infected in spyware. Since we were talking about Russia, how that place is which means word “Russia” was sent to spammers along with my email ID. Now these spammers send me those famous Russian Bride spam mails!

Even if we escape from first three possibilities, we cannot control what’s going on in our friend’s computer. Best thing to do is educate your friends about spywares, malwares, data miners and other bad stuff. You can also create an email ID only for signing up non serious websites and keep a private email ID for serious work.
