> 1. How do you stop someone from finding the actual property location by querying that map a bunch of times and averaging the positions returned? Back when YikYak was a thing, I was scraping the data for university campus through their API and found that their location data was randomized upon access. This meant that popular posts (they survived for longer) would end up producing pretty accurate location data. In one case, I confirmed this by walking into the computer lab in the building where the Geography courses were located and asked "who was asking for lab help on YikYak?" and one student sheepishly raised his hand. I helped him and then also gave him a lesson on real world applications of the central limit theorem. |
