Henley.com, Reznor.com. Is Your Name Next?

Here at Slashdot we tend to get certain things submitted a lot. Big companies going after "The Little Guy", especially regarding domain names seems to be one of them. Sometimes I feel bad for people because they owned trademarked names, but it looks like they are just squatting, but what about your name? Henley.com is being chased by Don Henley (thanks Netizen) and Reznor.com is owned by AJ Reznor being chased by Thomas & Betts. In each case, a person registered the name given to them at birth, but now a corporation wants to take it because they have a trademark. How do you protect your name?
