Only thing you can do is to convince the person who owns the PB banned account to appeal the detection at Evenbalance.
You can do this by making a support ticket here: https://www.evenbalance.com/support.php and provide the following details:
PunkBuster Server: VIOLATION (AIMBOT) #59140: Baikal_KpAcABa (slot #24) Violation (AIMBOT) #59140 [ac3aacec6be1ea67ddc1fae2c06f2141(-) 185.184.233.xx:1281]
If Evenbalance admits that this detection is a mistake, then we can remove both the bans.
For now,
