Don't waste your time reporting cheaters. EA stopped looking at these reports on Jan 4th this year. After this date, nobody is reviewing reports.
Before this date, I had reported more than a hundred cheaters and EA came back and confirmed that they have reviewed the case. This doesn't happen anymore.
The only thing you can do is to block the player but EA let's people have 3-4 different EA IDs so even if they would be banned, they can still play.
EA is not a serious company when it comes to cheating. This has been going on for over 10 years and they are doing NOTHING about it. They could easily ban 95% of the cheaters if they wanted to but they think they earn more money letting them play.
If you don't like this situation, the only solution is to stop buying this game. This is what I am doing.
