ahem................. here's a solo model paysite a few months older than Jewel, a first and last name domain name Taylor Lain
http://www.taylorlain.com - google 'Taylor Lain' - first result is TaylorLain.com - now go check out the page itself, next to none SEO on it
the fact of this matter is that if you DON'T want to battle with a thousand other SEO wise people for rankings on your own solo model site you give her a FIRSTNAMELASTNAME.COM
domain name and SEO isn't an issue.
