I was kicking around a definition involving trademarks. In general, owning a name that can be seen to infringe a trademark is a problem, no matter how you slice it. The Celtics baseball team have an actual, legal claim to the word "Celtics", which is not unlimited by any means, but is certainly stronger than "some guy registered this name on this site".
Now, had he been some sort of Celtic organization (and I mean the ethnic group, not the team) it might be a more interesting discussion, legally.
(And I'm just skipping out on the ethical issues.)
