Tried to hold myself from writing this as long as I could, but couldn't anymore. We're not lying, you're shit at the game. The other players killing you have been playing this game since it came out/for years hence why they know the basic spawns or pathways which are the most common or common camping spots - hence why they preaim and stay cautious while rushing (especially in HC). Another thing is get a headset (not speakers, but headphones) and you can see for yourself how loud you can hear enemy's footsteps when they're around you. Even having dead silence as a perk still generates loud enough footsteps for a decent player to have a general idea of your exact location.
We take player reports seriously but the clips you shared doesn't have anything suspicious in them.
