maybe teleport hack 

i have a video of it.

Considering the Video you guys "reviewed" banned the reporter for the guy is using teleport or spawn hack.

Ornsteinofblood CANT spawn at that position. Since the OBJ is JUST turned from blue to red in the video and not fully captured. Theres noone upstairs and theres no teammate of him in that corner or near that corner. There are even teammates from the video creater UPSTAIRS so theres no WAY for him to come through the window. The first enemy going up is getting shot from the creator of the video. And then this one gets shot out of nowhere from the left side.

If you guys really UNBAN that miserable cheat user..... wow then i dont know what happened to bf4db. But credibility isnt urs then anymore.

I've watched the video you posted on rheinfront and there was OrnsteinOfBlood, too. maybe it's the same video up there (it isn't aviable for me anymore). I saw it on 0.25 and he didn't ran up the stairs. so and he has no other way to get in the corner even he didn't teleport - like bro_u_mad_huh said, there is really no othre way - so as little tip, you know it ^^

I don't think he is still playing but there was something very suspect in the video and so you should check it out again if you "re-opened" this case - it's my personally opinion - a cheater should get banned even if he doesn't play anymore
