ThePlanet.com offers free server space - but want your credit card number anyway

ThePlanet.com offers free server space - but want your credit card number anyway. Why do so many companies ask me for personal information when they took up my time saying it is free? Potential ID theft certainly is NOT free! Actual ID theft is even costlier. I wish them success in their venture, but this is one I'll pass on. I've seen their posts several times today and have thought about it each time, but the answer is still no.
