Today I got ban at bf4, but Im dont know what's reason.

My battlelog - http://battlelog.battlefield.com/bf4/ru/soldier/zITriplxSIX-/stats/1495176290/pc/

My bf4db - https://bf4db.com/player/1495176290

Can someone help me?

You never got a ban from us

You're not banned by BF4DB, and I don't see any PunkBuster violation or other.

So that's more than likely a ban from some server admin. Try to reach out to them but so far there is nothing we can really do.
