Hello,
If you believe someone is exploiting the game you can report them on the Misbehavior Thread. Here is the link.

https://forum-narutoen.oasgames.com/page/show-post-52319-1.html

Please be sure to read and follow the instructions to ensure you are submitting the proper do*entation, information, and screenshots (for example, we will be unable to submit your current screenshots, thus making your current report null and void).
Thank you and have a great day!
