Has anyone ever been to
http://www.nissan.com ?
Well, it's not where you think it's gonna take you.
UNLESS the your site's name is trademarked.. AND the site in question has a product or service similar to yours, you got diddilly squat for a say.
In that case, it's definitely a snooze/lose situation.
I don't know how the heck thehun has gotten soo many people to hand over domains that are similar in name. I'm assuming that it's cause they had sites similar to thehuns.
BUT people, you can't copyright names.
If thumbzillas.com was a site about indexed thumbs of godzilla movies, thumbzilla the porn site has no ground to stand on.
Go ahead and ask Nissan Motor Co.
