just out of interest, what was the title that was copied?  I'm curious as to why you would feel you should have exclusive rights to use "that" exact wording in your 80 character title.  If a seller copied your description word for word then I could understand your angst.  Don't panic, I doubt that anyone here will start using your titles if you let us know which ones this thread is all about.

When I list film cameras my titles are usually "Pentax K1000 film camera with f2 50mm lens + bag, AS NEW" and I don't see why I should expect that nobody else should use this exact title if they are selling the exact same thing.
