Automatic duplicated activities detection
I have seen some users posting duplicate activities in Strava. Often due to the use of a mobile application and a GPS unit simultaneously.
I believe that most do this without any bad intention, but it is possible that some people are taking advantage of this opportunity to accumulate mileage greater than that actually traveled and using this on challenges or other reward programs.
Is It possible to implement a automatic verification process?
I believe that the simple check of the time interval of a activity overlapped by another activity entry from the same user would be enough to prevent this practice.
