Low chance if they use the in-game reporting thingy, unless there are numerous reports of you.
You should get banned in the first few weeks if they report you via email with solid proof, not some stuff where you randomly jump out and kill them.
Edit: I'm not sure about the via email thingy, there might be less or more reporters compared to a few months ago. So it might be a few days instead =P
2nd Edit: If you still wanna know how to check, go to the combat arms forum. Then go to the report section / user abuse section and search for your name =X
3rd edit: uh.. accident? o.o
