but we are talking here about 'fuckingsextube' and not about 'sextube'.
it has nothing with 'sextube' trade mark....
'nike' is trade mark also, right? so according to you any other domain that considers ...nike... can't be registered right?
if there is trademark on some name it means it can't be registered as it is on other extensions or it can't be registered with separators like fucking-sextube ...
if it is not like so then 98% of domains will be closed/deleted.
