Here in lay the issue, reporting people out of spite or hate. Has caused the reporting system to be back logged with petty reports. It will only take 1 genuine report if you were really cheating to get into trouble.

Failing that, the false reporting never goes against you no matter how many times you are reported if you are not cheating.

They divide the reporting into clusters, then run there programs depending on what report was made. If it gets to the human intervention stage, that's when people will get banned based on a closer look at the game footage kept on there data base. So I would say you have nothing to fear.

So long as it was not "Race hate provocication"
