Hi and welcome
Hotice12. Well, I think it's better not to go into too much detail for not helping cheaters who read this forum.

Just look at the graph carefully and ask yourself if it seems realistic. Same for the competition scores and compare the two when possible. However, sometimes you can not always be 100% sure if someone is cheating or not. All that we ask you is that you report any user that you think is suspicious. We take care of the rest.
If Chris is willing to give more information, I prefer he does himself.
