The post prompted comments from other users in the area. According to the author, the slips do not appear to be linked to possible fines, but rather to a kind of marker that could be used by thieves to determine whether vehicles are being moved.
In the same thread, another resident pointed out that the Local Police sometimes issue fines in the unpaved areas of the site. However, the author clarified that these are not tickets, but rather “spy papers” left by certain people to monitor the movements of cars and vans in the area.
