Is it legal to grab up domains and park them? Is it ethical? What about changing the TLD of a well-known website (nasa.com, for example)? With new TLDs being implemented, such as .biz, .bargain, and .tv, should all related domain names be protected? Suppose you purchase a domain name for your own use, and it turns out that a company wants to buy it from you? Is it legal to sell it to them? At a profit?
