The pros and cons of email addresses on a web page
Placing your email address on a web page is a very bad idea. As you probably know if you have an email address you can find your inbox being constantly bombarded with spam until eventually you have to just put up with it or change your email address. Placing your email address on a web page is inviting a whole pile of spam right your way. Just like regular search bots which crawl web pages and index them, there are bots that crawl web pages and look for email address using different techniques and add those email addresses to databases. Unfortunately once you are added to these databases and mailing lists there is almost no way to protect yourself from spam. Yes you can use various anti-spam email programmes to protect yourself, but even so if you receive a large amount of spam email every day some of it will probably still get through your email spam filters.
Protect your email addresses
You will find that email spammers use thousands of different email addresses and you can find yourself in a constant struggle cleaning out your inbox of spam messages about some crazy stuff. Even worse these spam emails can contain various viruses which can wreak havoc with your PC. A good rule of thumb is to never use your personal email addresses for any sort of correspondence with site visitors or the likes. An email address that you use for various important things like your web hosting or things like a PayPal account should remain confidential and only be used when dealing with companies you know are reputable. If you do want to use an email for correspondence with website visitors create an email address that is used only for this purpose and if it came down to a situation where the email spam is too much it can be easily changed.
Avoid placing emails on pages altogether
