Tons of cameras reported by one person on a 20-30 km stretch of highway. I've PM'ed the user and have already sent this along to support.

I have no idea what someone would get out of doing this; there's no points awarded for reporting cameras as far as I'm aware. But I think it might be a good idea to impose a limit on the number of cameras that can be reported from the client within a certain period of time, similar to the limit the Waze client imposes on hazard reporting.
