How many times a day you get those nasty emails that offer you “grow” something or buy something? As for me, I’m already tired of those letters, and you know what, there number gets worse and worse.
So how it happens that we get spam letters? That’s because somewhere on the web, at forums, blog comments or anywhere else, you’ve posted your email the way it looks firstname.lastname@example.org, without spreading it with brackets like this youremail (at) gmail.com or just blanks.
People who send spam (does anyone know how they look like?) use email harvesters, scrapers or email hunters, these programs have different names. Using this software one needs to provide a starting web site or starting keywords, and just let email grabber do the rest. It will crawl web site and collect all email addresses it finds.
So how to insulate yourself from spammers? There is a number of ways: you can use brackets (that's pretty old school) or email encoders, these scripts encode your email address into decimal and hexadecimal entities.
This is how my email looks when encoded:
To make it look like this email@example.com just paste the hex values into the code of the page and not a single harvester will track your email.
