[2020] Is there anything I can do if a hacker is on my team?

Originally posted by Heart Break: I have gotten my MMR deducted once because of a hacker, and I have also gotten MMR back from hackers, if I know they are hacking is there anything I can do to keep my MMR, or do I just lose it?

Report, and if you have some way of game capturing, record them cheating after you die and send it to Support[support.ubisoft.com] to they can handle it on their end.
