2 users corrupting tests with bad questions - may be the same person

A couple more users are corrupting the Google Search test. One named Lisa has added multiple incorrect answers and most of her questions (she's added 28) are trivia. I haven't done the Excel or Word test questions she's asked (and I'm afraid to, lest I hurt my score there too if she asked bad questions there). Stephanie has added 18 to both Google Search and Excel, also most of which are incorrect or trivia (or both!). Some of the questions are the same for both users, so it may be one person with 2 accounts.
