Hackers

I'm convinced the ingame "Report cheating" feature does nothing and is just cosmetics, nobody actually receives a report, I'm sure. If anything, I wouldn't be surprised for getting banned myself eventually for using it so often.

I also figure bothering with the provided form will be a waste of time, I used it several times to report cheaters in UFC 3, and while I always got a nice response, none of the people I reported ever got banned (I provided video evidence as well as explained what happend - see also here: https://answers.ea.com/t5/Other-UFC-Games/Please-do-something-about-the-cheaters-in-UFC-3-UT/m-p/9901525). It was said EA ditched Ultimate Team because people didn't tend to play it that much, but playing UT in UFC 3 myself still to this day, it's rather evident that 99% of the normal players simply left it because of the exploiters/cheaters, who ruined it for everybody and never got banned.
