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
