I used Whois.sc’s Domain Explorer function to find all registered names that ended in “sexechange.com”. There were dozens that were obviously meant to have meanings other sex change. But, the owners must have figured out the problems with them because about all are not in use. These are names like:
Comics Exchange.com (ComicSexChange.com)
VeteransExchange.com (VeteranSexChange.com)
MusiciansExchange.com (MusicianSexChange.com)
ActorsExchange.com (ActorSexChange.com)
ExoticsExchange.com (ExoticSexChange.com)
GraphicsExchange.com (GraphicSexChange.com)
HomesExchange.com (HomeSexChange.com)
KidsExchange.com (KidSexChange.com)
MomsExchange.com (MomSexChange.com)
PlayersExchange (PlayerSexChange.com)
WomensExchange.com (WomenSexChange.com)
StudentsExchange.com (StudentSexChange.com)
IOW,
if your name is a plural, don't call your site an exchange!
