Plain and simple.. This site is a business. If you are also a business and Spam this site, you will be gone instantly. I won't bother sending you an email explaining why. We will not accept any more "I didn't know" excuses.
If you don't have enough common sense to know better, you have no business even posting on forums yet.
Any more questions, read the rules found here. http://www.supermotojunkie.com/showthread.php?t=4034
