Anyone can report a listing,so it could even be a competitor,and as ebay can't physically authenticate items, they can be removed,so don't relist them again as they will now be flagged by ebay and it could get your account restricted.
While Vero rights owners can get items removed automatically,I don't see Hasbro on there list,but then the list is probably not conclusive.
