From WIPO on Fansites for UDRP:
2.5 Can a fan site constitute a right or legitimate interest in the disputed domain name?
This section only deals with fan sites that are clearly active and non-commercial. There are many UDRP cases in which the respondent claims to have an active non-commercial fan site but the panel decides otherwise.
See Helen Fielding v. Anthony Corbert aka Anthony Corbett D2000-1000 , Transfer
View 1: An active and clearly non-commercial fan site may have rights and legitimate interests in the domain name that includes the complainantโs trademark. The site should be non-commercial and clearly distinctive from any official site.
Relevant decisions:
Estate of Gary Jennings and Joyce O. Servis v. Submachine and Joe Ross D2001-1042 , Denied
2001 White Castle Way, Inc. v. Glyn O. Jacobs D2004-0001 , Denied
View 2: Respondent does not have rights to express its view, even if positive, on an individual or entity by using a confusingly similar domain name, as the respondent is misrepresenting itself as being that individual or entity. In particular, where the domain name is identical to the trademark, the respondent, in its actions, prevents the trademark holder from exercising the rights to its mark and managing its presence on the Internet.
