https://bf4db.com/player/1003023836192 - linked ban

https://bf4db.com/player/1039214056 - linked ban

And where is the link?

All these links, one person :)

you forgot this  https://bf4db.com/player/251646537 
When i report this acc, admin wtite "No Active BF4 Ban" & give him status "clean" 
But after re-reporting https://bf4db.com/forum/thread/rus-voron-smurf-accounts-2551another admin checked it better and somehow got to the bottom of the fact that this is a linked account. At the same time he said "Just because accounts have the same IPs does not mean they are linked. However, we've reviewed the links and I agree that these two accounts are linked"
