From Wazeopedia
To prevent cheating, Waze uses a throttling system. It is a mechanism which detects anomalies in the number of edits per time frame and prevents cheaters/scripters from gaining points for massive edits. While many scripts are used for positive additions to the map, some scripts cause specific harm with the goal of accumulating points quickly. Scripts used for massive edits are allowed, but may not always result in the rewarding of points.
==Editing using scripts==
The throttling system is in place to prevent cheaters from unfairly racking up points with massive edits. Waze is aware of the value that some scripts have to the map and are working towards identifying the behavior of these scripts vs. ones that are used exclusively to alter score.
