if its trademark issue related then it cost u mor ethan reg feee for the troubles that might come after u ..just let them drop n dun try to sell it , if trademark onwers find out they might file a case wif u.. if there are good they might just ask u to let them drop n not do anything wif it
or maybe even pay u some money if they are kind.. some will just demand the domain from u n u have to give them
