[Help] Vote Reward Issue ( having credits without clicking in the other side)

[AlikKk]

Het there guys, i have such problem in my server that when players want to Vote for Credits they dont even need to click Vote Button in the other side (Advertisement Websites), because they are able to get Credits after 10 seconds they click Vote Now in my website. There are already some players click vote button in the other side eventhough they know the logic. How can you help me? What should i do? Where is the problem?
