I'm not sure it would be possible to flag every thread that might contain an "offensive" word. They can appear in the middle of a thread during a discussion of slang and as Exx has said they can be completely acceptable in some countries.
Is it worth the trouble? To quote Exx again, this is not a scouts forum. We are adults engaged in work and learning. Should we really have to concern ourselves about the possibilty that a sensitive individual might inadvertently see a "bad" word?
It would seem to me that the best solution is to simply let each individual decide whether they want to remain in a thread after they have seen something that offends them rather than trying to "protect" them from the real world and warn them in advance.
