I find this to be a disturbing abuse issue by registrars as well... A good example is a domain I owned, <a href="http://thedigitalfreeway.com">thedigitalfreeway.com</a> ...it was owned by me and used for a webhosting business: 
<a href="http://web.archive.org/web/20060618003859/http://www.thedigitalfreeway.com/">http://web.archive.org/web/20060618003859/http://www.thedigitalfreeway.com/</a> but the business fell through as I had little startup money and was forced to close down and let the domain expire due to a ongoing ddos attack from china botnets that neither I nor my ISP had the hardware to handle properly (I didn&#39;t have the funds to buy such hardware). Since the domain expired now look at the whois info:
