I got a solution to fix all whores.
1: put them spec if you have admin.
2: Medic: Nade yourself most of your health then just keep taking the packs as a medic so they dont get xp.
Ammo: Shoot a bullet then take a pack. Be an ammo person for this so they dont gain xp.
Uniwhore: Follow them with nade launcher and nade launch the bodies so they splat and they cant be taken.
Do this if you have spare time and you see a whore and they will stop and get very pissed
