Thank you everyone for the information.

I am new and looking through the client exploring the tabs. I checked on custom play to see if I set up an AI match in there. However, a matchmaking game occurred and I closed out of it given I was not trying to do such with another player. Next thing I know, I got a popup stating I received one violation but closed it out before reading it. Where do I go to review the violation I received? Are they disputable?
