Okay so I found the battle reports, but when I click on them it says "FAILED TO LOAD REPORT Could not find the Battle Report in the Statistics engine" but I'll paste links to the battle reports anyway. Below, I'm also attaching screenshots of the servers that I went on that clearly say "trade kill" on them.

If there's any other proof I can show, please let me know.

How do I go about finding my battle reports?

I don't know if this helps at all, but my friend ParadoxBacon101 and I used to trade kill several years ago, but that was back in like 2014-2015 or sometime during then. I haven't done it since, but that's the only thing that I could think of that would cause that.

Here is my profile. I randomly started not being able to get on any servers without being instantly kicked for "suspicious activity" even though I've never used an aimbot or anything. I really don't get it. All I want to do is play BF4 with my friend but I can't because this stupid "anti-cheat" system thinks that I hacked or something. It's extremely aggravating and I don't deserve to be banned as I've never cheated... Admins please do your job and unban me.
