Can I prove I'm not cheating?

Three days ago, I was banned in Paladins: Champions of the Realm. I get reported with some frequency after matches due to hacking accusations, probably because I have decent aim and understanding of the game. One week ago, a twitch streamer told his viewers to report me — but I never expected I'd actually be banned from the game because of that.

I've already sent an email to Hi-Rez (the developer) requesting a review of my ban, and told them about the streamer. They haven't answered me since then, but I'm wondering if there's a way to prove I was not hacking/cheating? How?

If not, is there anything I can do other than sit and cry if they decide not to change my situation?

You should try to reach Paladins employees on Paladins Reddit or Paladins Official Forum.

If you can provide strong evidences that you are not a cheater (like the video where the streamer asked to report you, or your paladins guru profile to show that your skills are real) the community should support you and help you be seen by Hirez Employees.

Here is an example of what OP posted on Reddit which helped him getting unbanned.

The first step would be to contest the ban. When you make your case, provide as much evidence as possible, most importantly video or picture evidence, such as the clip of the stream you mentioned where they called you out to be reported. The second step is to just wait, and if you really need to, you can always make a second steam account.

It's very difficult to prove innocence in hacker accusations. They are essentially witch hunts. Most of the time hacks are detected and just banned on the spot there, but when player reports come in... it's their word vs yours. If they have a large number of reports against you, there's not much you can do to defend yourself.

All is not lost, though! If I remember correctly, Paladins does have a spectator mode that you can plug match IDs into and spectate various aspects. Find the MatchID of this game the streamer claimed you were hacking in, and send that to Hi-Rez as evidence. Using just the streamer's video may not help as it will likely only show their side of things.
