Opening More Than One Account Using Same Credit Card

Is it true that MSN Adcenter allows you to have up to 3 accounts PER credit card. See this link http://www.justin-cook.com/wp/2007/02/23/50-adcenter-promotional-code-valid-until-043007/. Its written that "A quick tip: MSN Adcenter allows you to have up to 3 accounts PER credit card. So, even if you have one account, you should consider opening up another for a free $45 (after $5 sign-up fee). "

 

Would be interesting if it were true. Have you tried it?
