This person speaks the truth.
Definitely do *not* ask for more money.
Agreed.
Whether a domain name can be taken off you depends on a number of factors, including whether there is any bad faith element to the registration. If you ask for more, it would support an assertion that the reason for the registration was precisely to chisel money out of the celeb. If you do that, exopect the dispute to be resolved against you and to end up with nothing. But .... if you're acting in good faith, then it can be tricky getting a registration away from a registrant.
I would either accept, or if you (Sinister, I mean, not you, Beany) do want to hold out for more, decline the offer but state the reason as something like the fact you are are developing a non-commercial fan site .... then do so.
You
might get an increased offer, or they might just accept that and sit back and wait, to see what the site is.
But any attempt to use a celeb's name to either commercially exploit that name, or to attempt a bit of friendly extortion on them, nearly always leads to the registration being unceremeniously transferred. Of course, if the offer is totally above board AND comes from someone other than agents of the celeb, then you could be on to a winner.
Oh, one more thing. Should a celeb really want their name out of your hands, Sinister, it isn't just about whether you'd win a legal fight. It's about whether you're prepared to stump up the cash it'll take to defend an action if one is brought. Are you? If not, don't push it hard enough that court looks easier or cheaper to those making the offer. The law really does belong to those that can afford to use it.
