When there are multiple police reports in the UK in one area it usually means there is a police checkpoint, recently there have been more in my area however me and my friends noted that the police also use waze themselves and press “not there” to remove warnings other waze users have put so that people do not realise and have to go through the whole headache of getting checked. A couple of ways around this could be that you require multiple different users to press “not there” before removing from the map or if a user has been stationary for awhile or pressing the “not there” abit too much even as other people are still liking the report it should be investiagted. The fact UK police are going out of their way to do this disgusts me. Maybe even checking the activity of certain accounts, if it seeming to be trying to remove the warnings. Luckily i believe they was not able to remove some of them however i noted alot of the hidden police markings from around the checkpoints seemed to just disappear and what i stated above is definitely why.(Police hide and radio if cars try turn, then make sure they definitely get pulled over)
