As of this moment, we filter out any AP that has been detected in two different places (where different means more than ~1km away from each other). This is very conservative approach and we'll relax that later. The real strategy is going to involve thresholds of a certain number of reports over a certain time period. For example we could change the "canonical location" after an AP has been seen 10 times over the course of at least one week in a new location. Potentially we could flag it as "dirty" after seeing just two reports in a different location and remove it from the search results, while we wait for more reports and "confirmation". The exact numbers will depend on the reporting volume and spam problems. Anecdotal reports suggest it takes Apple and Google about a day to realize your AP has actually moved.
