I think my friend is cheating.

As the title already says. I think a good friend of mine started to cheat in Escape from Tarkov.

We started to play this game together a couple years ago and he has about 1500 hours and I got 870 hours now. We always played duo together while streaming the game to eachother on discord. Since about 6 days he stopped streaming the game to me cuz the stream was "bugged" and "only captured" discord or made his game lag. He also jumped past me in those last 6 days progression and money wise. I am currently level 42, he was level 37 and now is almost level 42 too. He had 1.5 million. Now he got 28 million, found a red and violet keycard. Progessed EXTREMELY well through all his quests all of a sudden.His behavior in fights also drastically changed. He was a pretty good player before with a 4-5 average KDA if I remember correctly. But he is making some weird callouts claiming he heard footsteps when I didn't hear shit (I got higher perception than him).

So this is where the discussion will start. I stopped playing with him for now cuz I asked him if he was cheating and he is claiming that he isn't. Let's say he is cheating. Will I get banned as his duo mate cuz I played those raids with him and killed people that we possibly only noticed cuz of his weird potentially radar or wallhack callouts? I don't wanna lose my account cuz I love this game and this is my best progressed wipe so far. My goal is to reach Kappa for the first time.

Please refrain from attacking him or anything. I know its bad. Just give me your as neutral as possible thoughts for what I should do and if I could get banned for this.

EDIT : His PC is not that good so Streets is pretty much unplayable and Lighthouse is quite a laggy mess. That's why I mentioned the quick money gain. Yes I know that you can get a lot of money really fast from different loot runs 😀

EDIT : I heard from some people that the discord streaming bug is an actual thing that you are unable to stream Tarkov. So that argument is no longer relevant.
