Thanks! Great question.

1. Repeat votes - If you lose the vote, you can vote again. DIRT works not only for correcting intentionally misleading data, but also for fixing out of data information. It's similar to a bug bounty for data.

2. Cycle of challenges - Each time misinformation re-surfaces, you would have to challenge and vote down the data. However, every time you are successful in your challenge, you earn tokens for your efforts.

3. Fake news - Subjective information can be harder to adjudicate with DIRT and that will not be our initial market. As an engineer, I would love to believe that the blockchain can solve fake news. However, a lot of research shows it is not the lack of data that the issue, but rather perspective. People believe what they want to believe.
