maximum one report per X miles
Waze is awesome and everyone is using it. Some like me to navigate from Northern Denmark all the way to Romania on holiday others just to find out about speed traps.
In Romania, Waze caught a lot of media attention so we have a lot of new users, who are obsessed with the points. The new users part is good. We get more reports, more places, we improve on the map problems and we know exactly where the police is :)))
But then due to the point system, the new users instead of thanking for a reported police trap they keep re-posting the same thing a lot. This leads to 10-20 police reports for only one police speed trap.
In a village which was 1km long I've seen 13 police reports for the same police car. I generally look from time to time on the map, and even if it is a police marked on the other side I pay attention to the speed limit.
It would be nice to have a limit of reports per a certain distance. I've used other police trap apps and they were limiting the distance between the reports. This way you could only report another police trap if it as more than 1 km away from an already existing one.
This is also happening for traffic reports where on a stretch of 1km road you get 20-30 heavy/standstill traffic. This will only load the server and client uselessly and also consume more data on the end user and server.
SUGGESTION: Limit the number of POLICE (visible or invisible)/WEATHER/TRAFFIC/CAR STOPPED ON SHOLDER/ROAD WORKS reports to maximum 1 per 1km in both directions. If a user tries to post a new similar/identical report, use his report as a THANK YOU for the existing report and warn the user to use the thank you (thumbs up) button next time.
The pothole report should be left as it is, as you might have potholes 800m apart.

They actually do do this, only it doesn't seem to work all the time, and the constraints on distance are a bit too short, it should be expanded a bit more, but far less than you are suggesting.

Some other users suggested to limit also the number of reports per day based on your "trust level" and those whom get too many "not there" to be placed on a black list for a few days, but I'm not sure that is worth it, and that might give way to abuse.
