I've never squatted on a domain. Is the idea here that each year every domain would be subject to auction to the highest bidder? If so, that hardly seems fair that after having spent thousands of hours promoting a domain and invested in it that a spammer can come along and outbid me for my own domain. If the idea is that this should only happen when you first buy, it's similarly absurd. When you buy a domain there is only one person that wants it - you. Otherwise the domain is "not available". Also, no one made the domain. Why am I paying some third party for a domain anyway? It's not like their labor manufactured the domain.
