As others said, check tags as well as any words in the title. I had that happen when I used the word 'tusk.' It was just teeth from domestic pigs though, as described in the listing, hardly anything endangered, but they refused to revalidate the listing, the person I talked to just hinted hard that 'tusk' was the problem so I had to redo the entire listing, of course leaving out that word. Another time I had a listing deactivated that was rainbow colored large round magnets. Somehow they got it in their heads that it was a 'weapon' and would not back down on that listing either. This one was completely beyond my comprehension, there is no record or hint anywhere of any such kind of weapon, they are no such thing! No matter how hard you try, you will sometimes get in trouble for a listing for some strange reason it seems.
