All honesty just take whatever evidence/proof you believe you have and send it via a support ticket to LO.
Then sip tea/coffee/beer give a few days if the player you want banned is gone for more than a week congratulations. If they are still around perhaps you are wrong and need to get good and the person you think is cheating may just be that good at the game.
Nobody likes to lose and everyone wants to win and some have egos that cannot accept that someone just might be better than them.
Even players who have the worst score on the team yet scream at the top performing player because they lost the match yea think on that APB is full of poor performing players who think the problem is anyone but them.
Unless you are me and you like to see the world burn you can troll a bit.
However if you are blaming everyone of cheating and not trolling one bit you might just have issues with the butthurt.
