Thanks!

For the word hints there isn't a way yet, but this is a great point, I should add it in the future! For the sentence examples, it depends on what you mean with "bad". There's a "..." pop-up menu with an option to flag the example as incorrect or report it (for being inappropriate, abusive etc).

edit: For both cases, it is also possible to shuffle / fetch another suggestion.
