My high HSK is from TDM on Locker and some Market map on HC where i tested the weapons i mainly use in any game (shotgun, LMG, sniper):

On Locker (TDM or small CQ) (HC mostly with mixed Normal)
- I camped next to doors in the middle of the map on ground floor not where the unbreakable cells are.
- where the metal detectors in the corners where the stairs or the other corner where the door facing to a room with a switch to turn off lights.
-  (small CQ) camped (prone or crouch) in the middle of the map downstairs or leaned out when heard steps if i was close enough to the wall and standing.

On Metro (small CQ) HC mostly with Normal:
- between A and B a double automatic door which facing to the alley in crouching/prone in the notch in the wall
- prone or crouch at B next to the stair in the small room (in the corner or in the door which gives me best shooting position for one shot HS)
- both corners upstairs next to escalators at B
- prone at top of stairs left or right side

Also i used the slug on Market map (shooting out guys from the buses) in HC
- between C and D there is a building which facing to the buses there is only one entrance or one if you using the ledge to get onto the first floor (second floor if you are american) where i mixed slug and normal ammo on death.

Banreason:

Reason: Multihack

here is the one and only forum thread i was able to found https://bf4db.com/player/ban/713486971

Appeal:

I have no other bans in my BF history also i have more than 700 hours in BF1 (according to origin) also i have more than 1500 hours in  CSGO. so my aim can't be too bad even if we talking about a new game for me, and it is an FPS game. 

Additional Information:

I'm playing with my friend who has clean state in BF4 and he is teaching me in this game, i'm not a pro, i have no overwhelmingly good stat sometimes good sometimes not, also i like shotguns and camping in the face of the enemy.
