Using techniques to manipulate search engine rankings or to make money which offers no value to the user, like blog comment spamming where you leave a comment like "Nice post" just to drop a link.
Spam is the abuse of electronic messaging systems (including most broadcast media, digital delivery systems) to send unsolicited bulk messages indiscriminately. from: Wikipedia
Boo!!! sultanofseo you beat me to it. I was just about to say "pork luncheon meat" but you got there first lol
Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send -- most of the costs are paid for by the recipient or the carriers rather than by the sender.
I'm sorry guys. Had to comment on this one. I about fell out of my chair when I saw this! LOL Technically, that is spam.
The most common form of spam is unwanted e-mail. You can also get text message spam, instant message spam, and social networking spam. Some spam is annoying but harmless. However, some spam is part of an identity theft scam or another kind of fraud. Identity theft spam is often called a phishing scam.
Which makes her great to take to one of those slutty halloween parties! In all seriousness, SPAM sucks, everybody hates and its not a stable way to do business--especially if you get caught.
