I think i was banned because my m9 and g18 hskdr.
I know that these stats are a little bit ridiculous, but i have these stats because i got boosted by a friend to unlock attachments for the weapons. I only have such stats for those 2 weapons.

 My main k/d, skill and the kd on my most played weapon isn't that high at all.

Admin is probably gonna need the battlereports corresponding to the rounds where you and your friend boosted.

use bf4cheatreport.com, you can fetch up to 200 battle reports and sort by HSPK ratio.

That's gonna be so hard to find cuz it was like 1,5 years ago

Yeah its impossible to find, it was too long ago but i swear i only boosted for attachments, i have never cheated in this game

These two looks like boosting (from February 2016, guess that's what you're looking for)

This one howerer is more weird :

but I still think it's stat padding, you left server when people started to join in. Other reports during same period show almost 0% hspk :

Impossible, took me 10min to find btw.

It didn't show anything like that for me but yeah these are the games where we boosted

Sorry for the delay.

Stat padding.

Approved.
