Everyday software robots crawl websites all over the World Wide Web trolling for new email addresses to spam. When the robot finds an email address, on a web site, which could be yours, it adds the email address to its database. The spammers then use this database of email addresses to send spam, then they sell the database to other spammers. The topics in spam messages cover a variety of subjects including watches, pharmaceuticals, jewelry and products of a sexual nature. Although new subjects are solicited regularly.

Some spammers have special tools that they use to make your spam look like it is coming from a familiar person, including yourself or from a company that is familiar to you. They can also create subject lines for their emails to make them appeal to you, it is not until you open the email that you find that the subject has nothing to do with the contents of the email. This information can be gathered from your computer's browsing history, by the use of spyware, if your computer's virus software and security are not up to date.

Safety precautions must be taken for web site owners as well as consumers. Many web sites have email links on them for contact and inquiry purposes, they are important for business. If you want to post your email address on your web site, use an email ecrypter, before putting email addresses on your web site. A simple tool like this, will block spam from coming to you from your web site. This tool, an encrypter, allows email links to work, but they cannot be read by the robots.

When searching for an encrypter, try to find one that does not rely on having JavaScript enabled on your web site. Find an encrypter that works with any browser, one which uses ISO hexadecimal notation in its encryption would be best. This encryption formula translates the email address in to a format that cannot be read by the email harvesting robots.

Finding a spam blocking tool to encrypt email links on your web site would be very helpful in your quest to reduce the amount of spam that you receive. While we may never be able to completely rid our computers of spam, as technology evolves we are able to reduce the amount of it in our lives.
