1. What incentivizes people to report ? Social responsibility/concerns for others is the most common reason given when we survey people. For many people a proper case of food poisoning is frightening and extremely motivating.

2. On trust - crowdsourcing is imperfect. We have a track record of detecting outbreaks. Trust is case by case, for instance if you as a consumer choose to distrust our users, you are welcome to. What we tell restaurants is that our data is imperfect but we strongly recommend against ignoring it.

2. On scraping - For food poisoning reports we do not scrape public inspection reports. We do pull in external data for related (but not food poisoning) information such as temporary restaurant closures due to food safety infractions (vermin etc), or critical violations and fail grades. We also allow consumers to report high risk food safety observations, (raw chicken burgers etc). However these are just additional data points that our subscribers and consumers want to see, they are not part of what we use for detection. Though they can be correlated. No intention to blur the lines. It is actually on our to do list to come up with an elegant way of allowing consumers to separate if they want, and we definitely want a checkbox on our map, and also in our app. We also have in our queue a way for consumers to customize their email alerts to choose which data they get.
