Arrow Image A paper I had to write for University, so I figured I'd post it here too.

Spam can be defined as any unwanted message sent over the internet to a large number of users. The evolution of spam over the years has ranged from a simple message sent across Arpanet to modern spam, one which permeates every aspect of a user’s online life. Messages can be sent not only through email, but also through social networks, messenger programs, and even cellular devices.

Originally, spam was a simple email notifying members of Arpanet of an upcoming computer system release; however, modern spam is everywhere and provides little of use to anyone. Spam now runs rampant through the internet. According to major ISPs, seventy-five percent of all email is blocked because it is recognized as spam at the ISP level. These statistics do not account for the amount that makes it past the ISPs filters and is then blocked by email filters such as Gmail or Yahoo mail.

Email spam has become big business for underground hackers. According to, hackers even make contracts to populate spam using emailing lists bought on underground websites and internet relay chat rooms. Email spam has evolved from its earliest forms to a very advanced practice of evading filters to continue population; however, email spam is not the only type of spam populated through the internet.

Websites have become a large target for spammers. Forums are one of the most targeted because there is nothing stopping a registered member from posting his or her message in every thread. Another well-used tactic is to purchase domain names that are similar to a real web address and fill them with spam. For example, hosts a large number of clickable ads. Social networks are filled with spammers eager to post spam on their bulletin board or to your inboxes. False names and pictures of attractive girls are used to gain interest along with profile messages about common interests, lure users into believing that the member is legitimate, when they are really spammers. Email addresses and websites are not the only platform for spammers. Instant messengers and cellular devices also have become good targets. Instant message bots fill chat rooms, messaging random users. These messages generally advertise a website or webcam site. Cellular spammers can use simple programs to send messages to mobile devices. Most modern mobile devices allow email as part of the instant message platform. Addresses like allow a user to easily send a message to a friend, but these addresses are also brute-forced easily by a spam program.

With all these methods and platforms for attack vectors for a spammer, is there a way to defend one’s self from these masterminds? The short answer is no; there is very little chance that we will eliminate one hundred percent of spam without also eliminating some legitimate messages. However, there are ways for the spam-aware internet user to protect his or her self from larger amounts of spam. Using an email service such as Gmail or Yahoo will protect you more from spam than simple POP3 applications like squirrel mail because Gmail and Yahoo have spam filters that look for keywords or domain mismatches (email addresses such as coming from Another method that I prefer is to eliminate being added to a spam list being bought and sold on the “hacker underground.” These lists are generated by “web-crawlers” that look for email addresses in the html of websites. One good way is to post your email address only on sites that offer protection such as converting your email address from to member [at] place [dot] net. Better yet, encrypt the password with JavaScript. If you feel the need to post your email address on a forum or site that does not do this for you, you can protect yourself by modifying your email address in a way that a human would understand but an automated program cannot. Converting your email address from to will stop automatic spam bots from getting the correct address while a sentient user will notice the “nospam” and remove it from the address box.

In my opinion, spam will never be stopped fully; however, using basic rules to protect who gets access to your email address, using email address modifications, and not subscribing to “shady” emailing lists, we can eliminate a large amount of spam sent out. Spammers are constantly creating new and innovative ways to get their messages out. Likewise, we the users must also be constantly vigilant if we want to slow the spread of spam.

indeed. unfortunately, I'm sure once the spammers figure out how to use regexes, even the "member [at] place [dot] com" method won't work anymore. =P
